- Subject: Bug (or misfeature) report: cygwin setup behing caching proxy
I've been setting up cygwin on some local desktops here, and
was wondering why I was getting slow downloads even though I'm behind
a Squid caching proxy...
As it turns out, perusal of the squid log indicates that the setup
program makes its requests in such a way that the proxy cache is
bypassed and the files are directly fetched:
1027704003.367 3692 TCP_CLIENT_REFRESH_MISS/200 34258 GET ftp://ftp.nas.nasa.gov/mirrors/cygwin.com/pub/cygwin/release/sed/sed-3.02-1.tar.gz - DIRECT/198.9.9.17 application/x-tar
1027704010.780 7407 TCP_CLIENT_REFRESH_MISS/200 456543 GET ftp://ftp.nas.nasa.gov/mirrors/cygwin.com/pub/cygwin/release/sh-utils/sh-utils-2.0-2.tar.gz - DIRECT/198.9.9.17 application/x-tar
1027704016.212 5411 TCP_CLIENT_REFRESH_MISS/200 334645 GET ftp://ftp.nas.nasa.gov/mirrors/cygwin.com/pub/cygwin/release/tar/tar-1.13.19-1.tar.gz - DIRECT/198.9.9.17 application/x-tar
...etc.
Quoting from http://www.squid-cache.org/Doc/FAQ/FAQ-6.html :
-------------------------
TCP_CLIENT_REFRESH_MISS
The client issued a "no-cache" pragma, or some analogous cache control
command along with the request. Thus, the cache has to refetch the
object.
-------------------------
Is there some reason the setup program does this? I'd like to get the
files from my proxy server and ease the load on the public mirror if
possible.
Thanks!
