Hello,
after upgrading some proxies to a more recent release, i experienced
some sites not working correctly anymore.
The current proxy version i test with are:
Solaris 10:
Squid Cache: Version 2.7.STABLE6 (CSW packet)
Ubuntu 9.10
Version 2.7.STABLE (provided by distribution)
When accessing the following site:
http://www.fotofinder.com/
-> Search for any picture
-> Click a thumbnail
With no proxy enabled there is a picture on the left side and some text
on the right side.
With squid enabled, the picture is missing (broken link IE or no picture
at all FF), the text is there.
Example:
http://www.fotofinder.com/preview.ep?imagesid=821365&resultid=13&ownerid=281&searchresultid=02677e2b721ce1d3f0ed92485e9af07f&text=kiel&usrtrck=searchresult_link_icon_preview
Checking the link in the page i get:
http://imginfo.fotofinder.net/cgi-bin/nph-ffpic2.pl/?crossid=281&res=half&nomark=1&imagesid=821365&resource=extern
Calling this with the proxy enabled i get:
Invalid Response error was encountered while trying to process the request:

The HTTP Response message received from the contacted server could not
be understood or was otherwise malformed.
Some things from the access and cache log (maybe not related).

My questions are:
- Has anyone an idea what is causing this?
- Does anyone know how to generally "fix" this on the squid side (even
if the error webserver is in error), as older 2.x version seem to could
handle this (though maybe violating standards)
Best regards
Christoph
