[users@httpd] Question: ProxyPass not working??
Hi, folks:
On my websites, I want links like the following:
http://example.com/images/pic.jpg
silently grab the image from
http://192.168.53.93/images/pic.jpg [internal IP]
or
http://imgserver.com/images/pic.jpg [external IP]
example2.com(192.168.53.93) is a separate(physically) server where we
host all images on our website. in my httpd.conf, I've added.
ProxyRequests Off
ProxyErrorOverride On
<Location /images>
ProxyPass http://imgserver.com/images/
[I also tried the interal IP]
ProxyPassReverse http://imgserver.com/images/
</Location>
The above configuration did not work, I get 403 error by visiting
"http://example.com/images/pic.jpg", but I can access
http://imgserver.com/images/pic.jpg from web browser without problem.
[firewall enabled around our Internal NAT]
Really new to configuring ProxyServer, Can anyone tell me what I did
wrong or did I miss out some configuration that is necessary to make
the proxypass working..
Many thanks..
lihao

Hi, Eric:
Thank you for your input. I actually tested ProxyPass method and
Rewrite-with-proxy method separately. Probably I need to check why the
ProxyPass did not invoked? this infomation should be recorded in
RewriteLog file, right? ) really appreciate your time.. :-)
BTW. I am using Apache 2.2.3
Best regards,

In 2.0 you can't count on when proxypass and rewrite run relative to
eachother from system to system. In 2.2. and higher it's at least
explicitly coded (although I don't recall which comes first)
Don't mix proxypass and Rewrite-with-proxy for the same URL-space.
On systmes where by luck of the draw ProxyPass runs first, you might
see your rewriterules skipped.

Hi, Eric:
Thank you very much for your response. I've set
RewriteLogLevel 4
RewriteLog "/var/log/www/rewrite.log"
and found that Apache did not check ProxyPass rules at all. If I added:
RewriteRule ^/pics/(.*\.jpg)$ http://192.168.53.93/pics/$1 [P,L]
This worked as expected, but my questions are:
(1) can this hide the backend image server from outside? how can I check this??
(2) How can I make the ProxyPass work if I want to make some
fine-controls over the proxy..
Thanks again,
lihao

[users@httpd] Question: Which Directives responsible for 'Cach-Control' header?
Posted by Neil Simons <ne...@hotmail.com>.
Hi all,
I have a Fedora Core5 linux box running apache 2.2.2
When serving static files of certain extentions including .mp3,
'Cache-Control' headers are included in the response, as well as 'ETag'
headers etc.
My question is simply this: How can I stop the 'Cache-Control' headers being
generated?
I can successfully stop the generation of ETag headers using 'FileETag
None', but cannot find any documentaion on the control of the
'Cache-Control' header.
At this point, the following modules are disabled;
mod_proxy_
mod_cache
mod_expires
mod_mime_magic
mod_expires
mod_proxy_*

The one-argument form is used when you put the ProxyPass directives in
a <Location> block (because the other argument is divined from the
Location)

Hello;
At least one reason you are having problems is that the ProxyPass and
ProxyPassReverse directives are incorrect. these statements require two
arguments, not one. So try changing the lines to
ProxyPass /images/ http://imgserver.com/images/
ProxyPassReverse /images/ http://imgserver.com/images/
and see what happens.
