Hi Amos, IIS is adding the correct headers But Seems to me that squid removes them For example the Content-Encoding gzip is missing (thru squid)! ----------- Direct IIS ----------------------------------------------------------------------- I get this Cache-Control stale-if-error=1200, stale-while-revalidate=28300 Content-Length 7238 Content-Type text/css Content-Encoding gzip Last-Modified Mon, 20 Dec 2010 15:57:34 GMT Accept-Ranges bytes Vary Accept-Encoding Server Microsoft-IIS/6.0 Date Wed, 12 Jan 2011 16:39:29 GMT --------- Thru Squid ----------------------------------------------------------------------- I get this Content-Length 45868 Content-Type text/css Etag "2f0cb9e5ea0cb1:e6a8" Cache-Control stale-if-error=1200, stale-while-revalidate=28300 Last-Modified Mon, 20 Dec 2010 15:57:36 GMT Accept-Ranges bytes Server Microsoft-IIS/6.0 Date Wed, 12 Jan 2011 10:38:08 GMT Age 21775 X-Cache HIT from xx.xx.xx X-Cache-Lookup HIT from xx.xx.xx:80 Via 1.1 xx.xx.xx:80 (squid) Connection keep-alive Thanks In advance -----Original Message----- From: Amos Jeffries [mailto:squid3@xxxxxxxxxxxxx] Sent: Wednesday, January 12, 2011 12:48 PM To: squid-users@xxxxxxxxxxxxxxx Subject: Re: Squid & HTTP compression On 12/01/11 10:02, Leonardo Rodrigues wrote: > > squid 2.7 cannot handle HTTP/1.1 which is needed for, among other > things, the chunk encoding (compression) one.

Both doing de-coding chunks as required. Neither do any changes for the deflate/gzip/compress/sdch coding types. Both have roughly equal handling of coded variants. 3.1.10 and later have better ETag comparisons. > > Em 11/01/11 14:07, karj escreveu: >> Hello everyone, >> >> I have a small problem with squid (Squid 2.7.STABLE9). >> >> I'm trying to optimize our IIS6 web portal.

Absence of a header indicates there is no coding used on that object. Or are you saying that Squid removes the header without decoding? Amos -- Please be using Current Stable Squid 2.7.STABLE9 or 3.1.10 Beta testers wanted for 3.2.0.4
