[squid-users] Question about gzip Content-Encoding of IIS 6.0

Hi,all

our squid boxes run very well with gzip Content-encodeing (the source
server is apache v2.2.3) last days, but the trouble come in when we
add a IIS 6.0 server: gzip encode disappear...

    when i visit the pages on the iis 6.0, i see the data is encoding
with gzip,but when squid get data from iis 6.0, the squid decode the
data( or squid get the uncode data) and send it to the client without
compress,though the page displays without error.

    but all thing is ok when the source server is apache v 2.2.3: gzip
encoding in apache, squid and the client get the compress data.

   what's wrong? is the squid not support iis? or configuration added
is needed?

   thanks.

The header from squid with iis 6.0 parent (there are not lines of
"Content-Encoding gzip" and "Vary Accept-Encoding):

(Status-Line) HTTP/1.0 200 OK
Accept-Ranges bytes
Cache-Control max-age=60
Connection keep-alive
Content-Length 221686
Content-Location http://www.mydomain.com/index.htm

This is the correct header:
