You can have your IIS7 do static and dynamic compression though, and Squid will pass it. Extra hoop to jump through (From my internal wiki): ------------------------------------------------------ If you enable compression in IIS7, it won't compress for HTTP/1.0 clients, since encoding support in HTTP/1.0 is flaky. If we use Squid (and squid can handle it), you can force IIS7 to do compression anyway: c:\Windows\System32\inetsrv\appcmd.exe set config -section:httpCompression - noCompressionForHttp10:false c:\Windows\System32\inetsrv\appcmd.exe set config -section:httpCompression - noCompressionForProxies:false iisreset ------------------------------------------------------ -- With kind regards, Angelo Höngens Systems Administrator ------------------------------------------ NetMatch tourism internet software solutions Ringbaan Oost 2b 5013 CA Tilburg T: +31 (0)13 5811088 F: +31 (0)13 5821239 mailto:A.Hongens@xxxxxxxxxxx http://www.netmatch.nl ------------------------------------------ > -----Original Message----- > From: yaoxing zhang [mailto:yaoxing.zhang@xxxxxxxxx] > Sent: donderdag 19 november 2009 9:08 > To: sqlcamel > Cc: squid-users@xxxxxxxxxxxxxxx > Subject: Re: Gzip Supporting > > got it, thanks. > > Regards, > YX > > On 2009年11月19日 14:51, sqlcamel wrote: > > yaoxing zhang: > >> Hello everyone, > >> I'm using squid 3.0 stable 16 as a accelerator for my IIS 7.0 > server. > >> And I find that squid does not enable gzip for compressing, which > >> increases a lot of internet traffic.
