Proxomitron: highly flexible, small but very powerful, local HTTP web-filtering proxy

Proxomitron is one of the essential tool, everyone should use. It is better than Privoxy and Ad Muncher

I request you to post filters, questions, etc., in this thread.

FANTASTIC!
gotta try that

//edit: works! you can change my vote in poll to Yes now

1.) but hey, why it doesn't show normal images (not-attached to post) but as link eg. check here
http://my.opera.com/forums/showthread.php?s=&postid=799477#post799477

it can't work like that coz you can't see and click on link, it must be fixed

2.) can it resize big attachements to be smaller (fit to window) ?
eg. see this post -> http://my.opera.com/forums/showthread.php?s=&threadid=19033&perpage=40&pagenumber=10#post778382
I'd like to limit displayed pic size, is it possible and how?

1. As you see on Proxomitron log window it is requesting that image, but it is not loading. Usually some sites (geocites, tripod) don't allow images loading in other webpages to prevent bandwidth theft. It may be the reason.

in link I pointed above -> http://my.opera.com/forums/showthread.php?s=&postid=799477#post799477
she posted url to pic on http://www.imageshack.us/ service which allows hotlinking (they host images for free to put them at boards like this) so it's not that

plus, if it doesn't want to show image, ok, but why it doesn't show a link? I can even click it to see original picture...

2. Since we don't the size, it is difficult to resize the large images. But we can specify percentage of original size.

Replace = "width="75%" height="75%" border=5 vspace=5 hspace=5 alt="Linked image">"

can we go step farer and for example create clickable thumbnails?
because if someone will post tiny screenshot (eg. part of toolbar or smth like that) and it will resize it, it'll be more tiny, so practically invisible
people rarely post huge images (like desktop screenshots) so it could be solved if "fit to window width" would work all the time if turned on (but no, you always have to turn it again at all new opened tabs )

maybe there could be a rule in proxomitron filters to replace huge images to smaller and separate rule to replace small images to same size
then it would work perfect

1. As you see on Proxomitron log window it is requesting that image, but it is not loading. Usually some sites (geocites, tripod) don't allow images loading in other webpages to prevent bandwidth theft. It may be the reason.

In this case disabling F12 >> Enable referrer logging may help.

Proxomitron is essential to the way I use the web. I don't really use it for ad filtering, as I don't mind seeing well-behaved ad's. But I use it to rewrite cookies not on a white-list to be session only, and to control cacheing of pages to suit my needs. I use it to rewrite javascript that annoys me and lots of other little things.

If you were ever curious how the web worked, the HTTP header log is incredibly useful - as a web developer it can be considered essential. The ability to rewrite HTTP headers allows very powerful debugging of webpage problems.

Proximodo is looking very promising (works very well considering how immature it is - biggest issue is gzip decompression bug stops some pages loading), hopefully soon we will have the open-source proxomitron we have been looking for...

wow, you can do that!
attachement filter works perfectly now, fantastic, it should be like this by default in opera forum settings -> screenshot (those pics are clickable thumbnails, cool)
but I changed it to 250x180, looks better, see -> screen 1, screen 2, screen 3

but from some reasons external links show only blank white squares -> screenshot
(here is a link to example post, you can see does it work for you)

anyway, if external links don't want to display itselves then no problem I can resign from this filter, but attachement filter works superb, cheers

///EDIT: I just realised why
in above post user posted link to script displaying a file on imageshack so it cannot display a thumbnail, but I posted direct links in this post and it works well when I see them in preview post, but now I see it doesn't looks too good -> see how I see it
it mess the post form

but attachement filter is very handy and I'll probably make one for other forum too
cheers!

PS. proxomitron rid off some flash banners from sites I visit and that's ok but sometimes it rid off normal images which aren't ads and I'd like to see them; for now I click "Bypass" in proxomitron (or turn off/on proxy button on my main bar in opera) and refresh page but it must be somewhere in options I believe

can proxo change the background of certain forums to match them with this wonderful forum. I just love the colour of the opera forums, and find practically every other forum stupid with their black and blue backgrounds.

Using Proxomitron you could easily do per-site settings (which should be added to Opera ^_^)

Just write something which on site X replaces the stylesheet with stylesheet by you.

Does anyone know if it would be possible to make a filter which hides parts of this forum but unhides them when you click them?

if there was a class or id you could do it; inject a toggle script in the head, thn add onclicks to the elements. or even using only css and hover them...

I'm having problems modifying the attachment code for another forum. I have a slight knowledge of html so I know what I'm looking for on the source code it's just modifying it for proxo that I have the problems.

Here is the attachment source html

<td><a href="attachment.php?attachmentid=1930">6.jpg</a> (59.9 KB, 759 views)</td>
</tr>
<tr>
	<td><img class="inlineimg" src="images/attach/jpg.gif" alt="File Type: jpg" width="16" height="16" border="0" style="vertical-align:baseline" /></td>
	<td><a href="attachment.php?attachmentid=1931">13.jpg</a> (79.1 KB, 641 views)</td>

and here is the filter I tried to make

Name = "Show linked images [Alex]" 
Active = TRUE 
Multi = TRUE 
URL = "$TYPE(htm)&*.(sitename).com/forums/" 
Bounds = "<a*</a>" 
Limit = 512 
Match = "<a href="attachment.php?attachmentid=\1"\2.(gif|jpeg|jpg|png)</a>" 
Replace = "</br><img src=attachment.php?attachmentid=\1 border=5 vspace=5 hspace=5 alt="\2"></br>"

I remove the sitename due to it's dubious nature .

Any ideas what silly mistake I'm making?

Another thing the question I asked two posts above this, how would I do it?

Anyone who hasn't at least checked out Gryphen's set : http://computercops.biz/postt79253 has no idea what they are missing.

O MY GREAT GOD !! I KNEW PROXO was good that it cld strip the page for fast browsing, but i didn't know it cld modify google search results like that, or else strip hotmail( that was the best part)
THANKS A HELL jp10588, proxo is on my startup list and in my essentials folder.
i am using Gryphen's set. tell me what else does it do?

I've been using Proxomitron for years. I was happy with the popup blocking and thought of Proxomitron just as a popup blocker. I've just installed such filters, launched a Google search and must say that it is one of the most impressing things I've ever seen on a computer. Amazing. Every Opera user should try it. Unvelievable. Thank you very much for the tip.

wow, google got hacked now. great info at computercops.

@tamil, the attached image script/hack/code you have done, is there a way to apply this to all boards like a general rule, or do we have to create one for each board we want this to work?

because of the content of those boards, I cannot post them here. What about if you tell me where to put additional urls in your code:

$TYPE(htm)&my.opera.com/forums/

maybe a solution would be:

$TYPE(htm)&my.opera.com/forums/
&google.com/forum/
&yahoo.com/forum/

per say??? no?

okay, will do once I get home, thanks.

Where do I get the DeTabler filter?

Hey, any proxomitron hackers here have any idea how to carry the google changes in gryphen's set over to alltheweb.com and yahoo search?

is this site:
http://isnoop.net/gmail/

proxo removes that 'form' for typing ones email address
using gryphen's set. any solutions??

but i didn't know it cld modify google search results like that

is this filer in latest (?) "KyeUSecurityCollection.4.31.mergeme.cfg" ?
I downloaded it from Tamil link few post above http://my.opera.com/forums/showthread.php?s=&threadid=76301#post816979 and installed but I can't see anything with "google" in name provided with this pack

//edit oh I see you were refering to "gryphen pack", can you give me just straight download link linking to that 'google hack' file? there are 25 pages full of links and I really don't want to go throuh it
they write:

Latest version changes are always listed at the end of this topic thread so you don't have to read all the previous pages!

but I can't see any link in latest post there

thanx, I downloaded it and installed but the problem is I can't really see differences in google results
I also noticed there's picked "Google - Mark results" filter but it doesn't work too (I guess it should mark results as they look in "cached" view)

google proxomitron.png

no, I don't know but it seems to be disabled or smth
as you can see in my attachement I marked few things to let you see that

- Proxomitron is running
- Proxy is set up
- I typed Proxomitron
- 'Web Page Fiters' is active

this is what i get.png

Have you went into preferences|network and clicked on proxy servers? If you havn't you need to set it up so it looks like the attached screenshot.

proxy_settings.png

as you could see on my screen, I have "Proxy" button enabled
I have all of those settings (no 127.0.0.1 but "localhost" but it's the same)
I may try with digit values too but it would be strange if it would be this coz I use proxomitron longer time and it always worked with these settings

//edit it works now but I just realised I had checked option: "don't use proxy for following adresses:" and one of them was google

Well isn't this a nice surprise. Glad y'all like the google filters.

We love them, now if you could give us a hint on filters for Yahoo and AllTheWeb that do the same... +1:up:

Don't use it. No Linux version. Usage under wine is not an option, but an open-source version for Linux and Windows is being developed. It's called Proximodo. Linux users need to compile from source (no binaries yet) -- project is in stage 3 (alpha).

When Proximodo can import the advanced JD5000 deriavitive sets, then I'll use it. For the 90% or so of people on windows, proxomitron is GREAT. Otherwise, I am waiting with baited breath for Proximodo to get out of alpha (and hopefully import filtersets correctly).

Is it just me or using a proxy (Proxomitron, in particular) degrades significantly Opera's cache performance?

It seems to me that when I use Proxomitron as a proxy, Opera's cache works much worse than when there's no proxy. If I open a page with many images (Proxomitron running, proxies enabled) and reload the page several times Opera seems to make many more requests on each reload than if I do the same without a proxy.

For example, I tried this page: http://www.opera.com/docs/screenshots/
I reload several times with proxies enabled. Each reload takes 2 to 3 seconds, and all the images are visually redrawn. Opera makes 28 HTTP requests on each reload (the log in Proxomitron shows this).
Then I disable proxies and start reloading the same page again.
Each reload now takes 0-1 seconds, there's no image redrawing. By looking at the statusbar in Opera, it seems as though Opera is making a single request to the server - just to receive a response that the document hasn't expired, I suppose. Visually the whole "Press F5 - Page fully reloaded" cycle takes much, much less time.

And the same thing happens for virtually every page, it is clearly noticable when the images are more than 2-3.

I have set Opera to check cached documents every 5 hours, images - 24 hours, others - 10 hours, HTTP 1.1 is enabled for proxies (and doesn't seem to be relevant), toggling "Local connections persist for" in Proxomitron also doesn't change anything.

This thing has stopped me from using Proxomitron for now. I would really appreciate it if you can confirm or give me a tip on how to fix this behaviour.

Did you tell Opera to use http 1.1 (pipelining) for proxies in the network settings? That ought to fix that problem. Also, in gryphens latest set (linked to some extent in my sig) there are new z12(author sn) caching filters that set more agressive caching.

Yes, I mentioned it - http 1.1 is enabled.
The problem seems to be that Opera is making much more requests to the proxy (with proxy enabled) than it makes to the server with proxies disabled. I'll try gryphens set to see if it will fix things.

Well, I do use another proxy for agressive caching - allegrosurf 4.4(old I know, but works). I find it works very well for not reloading things that don't need to be reloaded, vs those that do.

Anyway, using just Opera (proxies unchecked) I get similar results to with them checked. Out of 4 reloads, 2 there was a flicker on the images, once they were blank for a second, once - as if I didn't reload at all except for the flash of the progress bar.

Using the proxies, I had 3 times with a flicker, and once with no visual indication of reloads except for the progress bar.

Seeing as my connection or whatever sometimes causes flickers or visible reloads of the images sans all proxies, I don't see it as being proxy related (or my machine just works differently).
