Hi We have Squid in the main site and it is delivering content gzipped perfectly but on the forum when we have HITs (always guests) a lot of the times (maybe most of them) the content is delivered without the gzip header. The webserver is lighttpd and gzip is configured in vBulleting settings (not in lighttpd) https://www.vbulletin.com/docs/html/vboptions_group_http . If we try to get the content directly to webserver without Squid it is delivered in gzip perfectly. We have added this code to Squid.conf but is still not working properly: acl apacheandlighttpd rep_header Server ^(lighttpd|Apache) broken_vary_encoding allow apacheandlighttpd On the main site we have apache with mod_deflate and this code in Squid.conf and it is working perfecly: acl apache rep_header Server ^Apache broken_vary_encoding allow apache Any idea an what's going on or any recommendations on how to proceed to find the problem? -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/gzip-with-Squird-working-fine-with-our-site-but-not-with-our-vbulletin-forum-Any-advice-tp3862015p3862015.html Sent from the Squid - Users mailing list archive at Nabble.com.
