Certain URLs are inaccessible, i.e. when visiting

http://www.msnbc.msn.com/id/25640691/&GT1=43001

I get the following error:

"Too large Chunked-header received (>256)"


This issue pertains to HAVP 0.87 and 0.88. This issue does not exist with HAVP version 0.86 (i.e. the URLs are accessible when running this version of the proxy).

It seems this broken IIS wants "Via:" header to behave properly.

Without it, it sends:

Content-Encoding: gzip
Transfer-Encoding: chunked

But it doesn't send it chunked, just the plain gzip data.

You can set X_FORWARDED_FOR true (less privacy) or try this patch which sends plain Via: even when disabled.

Code:

     return header;

Great, this appears to have resolved the issue.

Thanks
