Yahoo mail login wallpaper
Yahoo mail has started inserting a large wallpaper-style backgound on their login page. Example image here.
I've been unable to filter it using the AdHosts list, which is the way I typically eliminate specific unwanted backgrounds. Enabling "Use SSLeay/OpenSSL" and adding libeay32.dll, ssleay32.dll, & msvcr70.dll to the main Prox folder hasn't helped. In fact I've never had any success filtering unwanted Yahoo mail code. What am I doing wrong?

IIRC, you see
https://s.yimg.com/lq/a/1-/java/promotions/t/login/100617yhp/tie4.jpg but The Proxomitron sees
https://s.yimg.com:443/lq/a/1-/java/promotions/t/login/100617yhp/tie4.jpg
Note the addition of the port number, :443.

So try adding something like
Code:
s.yimg.com:&*/login&*/promo*.jpg&$RDIR(http://local.ptron/killed.gif)

to your 'user' list, Exceptions-U or Include-Exclude-U.

RE: Yahoo mail login wallpaper
I added that to Include-Exclude-U, reloaded lists, cleared cache and then clicked my example link above, but it did not block it. In fact, the log showed no activity at all.

I'm confused. Why should the image be redirected to another image? Why not just prevent it from loading via AdHosts? I'd prefer a blank background anyway.

Not sure where the :443 came from and why

Is the "&" symbol used just in case "promo" and "login" are someday reordered in the URL?

Have you set the browser to use the Proxomitron for HTTPS?

killed.gif is a transparent or blank image. Proxomitron's \k works like this.

You might but I don't see your issue at Yahoo mail. I couldn't be sure it would work.

(Jul. 02, 2010 03:49 AM)zoltan Wrote:  Not sure where the :443 came from and why

443 is the default port for https. When you don't add a port, :443 is added for you.

RE: Yahoo mail login wallpaper
The browser was only set for localhost 8080. But now when I added localhost 443 in the SSL box, the yahoo login won't work. It just gives an error message: "Firefox is configured to use a proxy server that is refusing connections."

Well, I just want to prevent the .jpg from loading. That list has always seemed to work for non-https sites. Does https change the function?

Proxo is at port 8080 for HTTP and HTTPS. So in the SSL Box you would add the same info as the HTTP box.

443 is the port on the yahoo server that your computer will try to use.
80 is the default port for HTTP.

No.
There are two ways to prevent the .jpg from loading.
1. Remove the code that calls the jpg from the page's HTML. The browser can't request what it doesn't know about.
2. Intercept the browser's request or the server's response for the jpg and block, redirect, or modify.

I can't be sure adding to AdHosts removes the code from a page that I don't see.
I can see that adding to Include-Exclude-U blocks or redirects my access to the address that you provided.

RE: Yahoo mail login wallpaper
After adding localhost 8080, Firefox (and Proxomitron) is now responding with a series of warnings/errors.

.gif  prox ssl.gif (Size: 30.37 KB / Downloads: 495)

After going through all of them and choosing "allow" in the Proxomitron box, I get different results depending on which list I use.

With Adhosts, it still loads the image. With your code placed in Include-Exclude-U, it loads the login page (without the jpeg) but only after going through the Firefox warnings and clicking "allow" numerous times. Is this unavoidable, or is something still wrong?

Sorry to be dense, but I still don't understand the Adhosts issue. When you say "... a page that I don't see," do you mean that the yahoo login page or the image that I'm seeing won't load for you? The first method you listed, removing the code that calls the .jpg, would seems to include 1) writing a new web filter that matches/replaces the jpeg's URL, or 2) adding that URL to one of the lists that can block it.

RE: Yahoo mail login wallpaper
there are two ways around the ssl warnings/errors...

1) http://prxbx.com/forums/showthread.php?tid=1618
2) using "half-ssl"

i use "half-ssl" but the ProxHTTPSProxy has been on my to-do list, i've trial-ran it in several of its earlier versions, but haven't been able to return to it - yet...


with #1, you need (?) OpenSSL installed (the thread is fairly lengthy, but patience and time to read it through will get you up and rolling)...

with #2, you need the OpenSSL dll's copied over to Prox's "home directory"...


i only use Firefox for debugging purposes and not for day-to-day browsing, so "mileage may vary" Big Teeth

I don't see Proxo complaining. Have you updated the certs with certs.zip at http://proxomitron.info/files/index.html ?

I do see Firefox warnings. Some, maybe most, may be avoided as ProxRocks has noted. Removing unneeded https addresses also avoids the warning, of course.

My yahoo login page did not have a link to a background image. I had text. Sidki's set removed the text, iirc.

Code:
Welcome to Yahoo!

    * Stay in touch with free Mail and Messenger.
    * Protect your PC with free Anti-Spy and Pop-Up Blocker.
    * Get weather forecasts and current conditions for your area.
    * Tune in to the latest in music, entertainment, and sports.

Get all the best with one Yahoo! ID.

Your Yahoo! ID gives you access to powerful communications tools like mail and instant messaging, security features like email AntiVirus and Pop-Up Blocker, and favorites like online photos and music all for free.

However, I have found a page that has a link to a background image.

In the login page's html there is code like

Code:
<div id='iframeHolder'>
<iframe id='adFrame' src='https://login.yahoo.net/login_superads/superads_iframe_content.html?es=alphanumerichere' frameborder='0' scroll='no' height='1200' width='1920' onload='loadTime = new Date().getTime();'>
</iframe>
    </div>


The ?es=alphanumerichere in the address probably changes and may be unique, I haven't checked.

'https://login.yahoo.net/login_superads/superads_iframe_content.html?es=alphanumerichere' contains text or background image depending on something.

A 'https://login.yahoo.net/login_superads/superads_iframe_content.html?es=alphanumerichere' page with a background image has

Code:
<style>#richad{height:926px;width:1340px;overflow:hidden;position:relative;margin:0 auto;background:url(https://s.yimg.com/lq/a/1-/java/promotions/t/login/100617yhp/tatoo2.jpg) no-repeat -26px top;}</style>

Correct. Lets try for the "2)" with AdHosts but sidki may prefer another way.
The filter we want to invoke is "CSS: Remove Ad Backgrounds"
It uses AdList which calls AdHost. AdHost warns

Quote:To match it must be followed by a boundary: a dot, slash, dash, or end-of-string.

and provides

Code:
#    For CSS backgrounds ("CSS: Hide Ad Backgrounds" filter):
#      $TST(\3=d)

We are hunting addresses like

Code:
s.yimg.com/lq/a/1-/java/promotions/t/login/100617yhp/tatoo2.jpg
s.yimg.com/lq/a/1-/java/promotions/t/login/100617yhp/facebook2.jpg

Lets try adding

Code:
s.yimg.com/&*/promo&*/login*.jpg&$TST(\3=d)

to AdHost. Result

Code:
<Match: CSS: Remove Ad Backgrounds     6.12.19 [sd] (d.2 l.3) >
background:url(https://s.yimg.com/lq/a/1-/java/promotions/t/login/100617yhp/facebook2.jpg)
</Match>

Now my question is how are you seeing the background image?
I think sidki's sets stop this by removing access to 'https://login.yahoo.net/login_superads/superads_iframe_content.html?es=alphanumerichere' and maybe could by modifying some headers.

Have you added entries for login.yahoo.com to you user list?

Note that unlike header filters where we must remember the :443, Web page filters must match what is on the page.

No, I still had the original certs. But now with updated certs AND Proxomitron.exe (from 5/22 to 6/1) the Prox warnings have disappeared but the Firefox warnings persist.

Yes, I get the code that includes iframeHolder with the superads on the login page. Not sure why that would be different for others, but maybe it's location specific.

I do have CSS: Remove Ad Backgrounds enabled. If it requires other filters to be enabled maybe that's the culprit. Seems like I remember having to enable or disable something rather important several years ago to get the background dimmer to work, but I can't remember what it was.

"User list"? Like User-Agents? There's nothing about Yahoo in there.

Now after adding s.yimg.com/&*/promo&*/login*.jpg&$TST(\3=d) to Adhosts I'm getting a Proxomitron exception error that pops up every time I click FF's "try again" so the page won't load at all.

Hmmmm. I didn't anticipate that it would be this difficult. I'd like to avoid helper apps because I've gotten several friends to use Proxomitron and I supply them with updates and customizations from my config/lists. Yes, I know, I'm not exactly the most qualified for that, but the program with sidki's filters does some incredible things and I'm the best they've got. It's hard enough to convince people to use it at all, but I think an additional program would be an even tougher sell. From what I read above, it looks like I'm stuck with the warnings when filtering https. If that's the case, maybe the best decision is to not filter.

Sorry, I meant Include-Exclude-U. I see sidki's set removing or modifying the code in iframeHolder. For me, 'CSS: Remove Ad Backgrounds' wasn't needed to remove image. I had to disable some filters to be able to test my Include-Exclude-U entry for 'CSS: Remove Ad Backgrounds'.

I think the changes that you have made may be the reason you see the background image. Do you see the image with an unaltered sidki set or the sidki_oob cfg?

My disabling of filters could be the reason I don't see the exception error or your changes could be the reason that you do or it could be unrelated but it's tough for me to help. ;-)

The warnings are a good thing but a pain, in this case, since we don't really need to be warned about the Proxomitron.

The helper apps a tough sell. Half-SSL does miss and when it does there is a warning.
But there is also the question of your friends filtering banking, shopping, and other important ($$$$) sites...

With https filtering + the new adhosts entry? or are the original settings needed to test this? I loaded the oob config and disabled "use SSLeay..." and the image loads. With "use SSLeay.." enabled, the image doesn't load, but FF gives warnings.

The only yahoo-related entries in Include-Exclude-U are:

de.mc256.mail.yahoo.com                    $SET(0=a_code.)
www.yahoo.com/   $JUMP(https://login.yahoo.com)
my.yahoo.com/   $JUMP(http://mail.yahoo.com)

Half-SSL works by hiding the https from the browser. Proxomitron handles the https and feeds the browser http. A sidki set Half-SSLed link for 'https://login.yahoo.com/' is 'http://https-px-.login.yahoo.com/'. FF will give warning for the first but not for the second.

You or the Proxomitron's web page filters must provide the Half-SSLed links.

I don't see warnings when logging out but the yahoo logout pages that I have seen probably use different code than yours.

I rarely see warnings but I don't use many https sites.

So - in case you've decided to test an alpha or beta version - submitting your Log-Rare entries (anonymously via this submission form) is sort of mission critical. Wink

RE: Yahoo mail login wallpaper
Until there's a better solution, I'll probably just not filter https. With a day or two of experimenting I've found there are just too many instances where Firefox requires adding exceptions to untrusted connections.

Looks like it's time to investigate the alpha. But I just checked the current Log-rare (which I never do). Lots of entries - it's up to 123k.

Thanks for all the info.
