Hi,
I have set up squid in reverse proxy (http-accelerator mode) on a machine
along with the web server. the web server listens on 127.0.0.1 while squid
listens on 192.168.124.41. There is another web server 192.168.124.40. Squid
has been configured with urlpath_regex to redirect any incoming requests
with "images" in the url to 192.168.124.40.
|---> webserver1 (127.0.0.1)
squid (192.168.124.41) --- | |
|---> webserver2 (192.168.124.40)
Now according to my config, pointing my browser to
192.168.124.41/images.html should lead to 192.168.124.40/images.html. The
page loads up but the embedded images do not show up. A tail -f on
access.log shows
1330494519.583 5 192.168.124.41 TCP_REFRESH_UNMODIFIED/304 357 GET
http://192.168.124.41/images.html - FIRST_UP_PARENT/server2 -
1330494519.814 3 192.168.124.41 TCP_MISS/404 582 GET
http://192.168.124.41/myimage.jpg - FIRST_UP_PARENT/server1 text/html
images.html has an image embedded in it called myimage.jpg. Squid does well
to redirect incoming requests for images.html to server2 but it is still
looking for myimage.jpg on server1. Why is this happening?
Thanks,
Adi
I have reproduced squid.conf below
