Post by: zivilist on August 17, 2012, 04:25:07 PM
Hello avast team,

loading all webpages have no problem, except www.synology-forum.de (it is a vBulletin based forum)
when web shield is enabled.

OS:
OS X 10.8

System:
iMac mid 2010
Core i3 3,2 GHz
21,5 inch
8 GB RAM

The problem is, that www.synology-forum.de (http://www.synology-forum.de) sends broken HTTP responses when the browser supports gzip content encoding. It sends a Content-Length header value of the uncompressed data where the size of the compressed data must be send. However as there are more such broken servers on the internet (http://forum.avast.com/index.php?topic=100557.0 (http://forum.avast.com/index.php?topic=100557.0)), we will see if we can find a workaround for them.

Well, there is no need to disable gzip content encoding, it must only be done properly according to the HTTP standard. But I suppose this is just a temporary solution until they fix their server configuration/content generation logic.
