Question Issue with Amazon.com redirects and back button which Bypass fixes
Using: Proxomitron 4.5 with no special config sets, IE 8, SandboxIE, Windows 7.

Hi, I have been using The Proxomitron for years and have finally run into an issue I can't write my own filter for, or at least don't know where to start. The problem is with Amazon. If I click a product, it goes to that page, but then my back button does nothing, I can't get back to the original page without clicking the history arrow and selecting the page I want. What happens is there are two interim pages that don't let me go back past them. For example from the front page I click on a drill my history will show:

Amazon.com: DEWALT DC742KA Cordless 12-
http://www.amazon.com/aan/2009-09-09/st
http://www.amazon.com/aan/2009-09-09/st
Amazon.com: Online Shopping for Electro

Then to go back I have to select in history the entry before the two /aan/ pages. If I bypass proxomitron then the problem doesn't happen, in fact the two /aan/ pages don't ever show up in my history. I've also cleaned cookies and other simple browser tricks. If I look at the log window nothing comes up with /aan/ in it.
Anyone have any ideas? Anyone else have this issue?

I can't replicate.

What happens after you add

Code:
[Patterns]
Name = "test"
Active = TRUE
Limit = 2560
Match = "<div id=\'cachebust*</div>"

to the top of your webpage filters?

Intended to remove

Code:
<div id='cachebust_342667_adcontent' style="width:301px;height:270px;margin-top:0px;margin-bottom:16px;overflow:hidden;"> <iframe src="#" id="cachebust_342667" scrolling="no" allowtransparency="true" marginwidth="0" marginheight="0" frameborder="0" width="301" height="270">></iframe> <script> (function(w,u,f,c,n){ function x(){if(_ued)uex('ld','display-ad-right-2')} f=document.getElementById('cachebust_342667'); try{ (w.aanParams=w.aanParams||{})['right-2']='site=amazon.us;pt=Gateway;slot=right-2;pid=507846;prid=0TENPAXATHXAGC5JAWNH;arid=1cbb5b848b5d45c3ab00fba1a6937bc1;ef=0.05'; w.d16g_dclick_right_2_863_0='amzn.us.gw.atf;sz=300x250;bn=507846;u=1cbb5b848b5d45c3ab00fba1a6937bc1;ord=0TENPAXATHXAGC5JAWNH;s=i0;s=i2;s=i3;s=i4;s=i5;s=i6;s=i7;s=i8;s=i9;s=939;s=448;s=534;s=533;s=944;s=67;s=24;s=143;s=1009;s=32;s=16;s=u4;s=u5;s=u10;s=m1;s=u17;s=m4;z=3;tile=1'; c=f.contentWindow.document; c.open(); c.write("<body onload='document.location=\""+u+"\";'>"); n=0; f.onload=function(){if(++n==2)x()}; if(_ued)uet('af','display-ad-right-2'); c.close(); }catch(e){ f.onload=x; f.src=u; } })
(window,'/aan/2009-09-09/static/amazon/iframeproxy-5.html#zus&cbright_2_863_0&eCM'); </script> </div>

from the source code.

RE: Issue with Amazon.com redirects and back button which Bypass fixes
That didn't work. I'm really scratching my head over what I could be doing differently then everyone else.
I upgraded to IE 9, which didn't help. I tried logging out of Amazon, didn't help. I have flash installed but disabled, same with silverlight, enabling them didn't help. But if I bypass proxomitron it works. I just downloaded a new copy of 4.5j and run it with all default settings and it still happens. If I run Mozilla though the same proxy it works.
I'm just baffled.
Ok, to baffle me even further, if I add *.amazon.com to IEs proxy Settings Exceptions, I Still have the same issue. Amazon looks fine but the back arrow still doesn't work, but bypass fixes it. So Amazon must be using another site.
Ok, looking at the log window there seems to be two gets to ad.doubleclick.net. But my browser history clearly says the two ghost pages on amazon.com.

Could these be the issue?

MR_yeoman and MR_yeoman2?

Amazon advertising (html) may target customer's ip addresses.

Address for traffic through the Proxomitron may be seen at http://local.ptron/.pinfo/urls/ .

Actual behavior depends on the browser but (I think):
Browser history may be modified by javascript, "document.location.replace".
Meta "refresh" and javascript "window.history.forward" may defeat the Back Button or (in the latter) slow it down (as clicking more than once may get desired result).

So Mozilla Proxo works, IE No Proxo works, but IE Proxo doesn't work.
I suspect that Amazon tries to A>>B>>C and 'fix' thing so that back button gets C>>A. Your filters are somehow breaking their 'fix' for IE Proxo.

I thought removing the code that I pasted before might help. It contains "/aan/2009-09-09/static/amazon/iframeproxy-5.html#zus&cbright_2_863_0&eCM". The address that you pasted contain "aan/2009-09-09/st". Did the filter match anything?

I think the two log entries are for blocked images. I don't think they are part of the problem.

I played with this for a while longer and then just decided to live with it. Then today it started working correctly again. My guess is they where doing something a little too clever and then fixed or changed it back. Thank you for the help. Hopefully they don't unfix it.

Having no better answer, I'll agree to that. Wink There were others complaining and I doubt that they all used the Proxomitron.

Well I tried. Fingers are crossed.

Have fun.
