mod_rewrite question

Hi

I've recently got mod_rewrite compiled and configured for Apache on my
webserver machine. It's working fine, i know how to configure it, and so on.

I'm hosting my own website from home, but have placed images onto my
ISP's webspace and configured mod_rewrite to "rewrite" any URL's that
are in the image dir (/img) to look on my ISP's webspace.

Now, when people browse my site will _their_ browser grab the images
from my ISP, or will _my_ webserver grab the images and send to the web
broswer?

The reason i setup mod_rewrite is to save my bandwidth, i.e. images are
downloaded from my ISP. Does this make sense? Is this one of the things
that mod_rewrite can do? If not can anyone recommend what i can do?

TIA

Ben

both is posible.

if you used the [R] flag for RewriteRule, or none at all, since it is
an external absolute uri, the users browser will get a redirect and
fetch the image from the given location.

if you use [P] which is only available when mod_proxy is loaded,
apache will work as a reverse proxy and fetch the image itself before
delivering it to the user - double bandwidth penalty...

Here's the rule i used (yes it's without [R]) :-

RewriteRule ^/img/(.*)$ http://www.benzalez.plus.com/2halfsimg/$1

When i load the page in my browser i can see the status bar quickly
flash "connecting to www.benzalez.plus.com", but when i do a view source
images still show as "img/whatever.gif".

I take it when the broswer asks for "img/whatever.gif", apache then
sends back a redirect to the www.benzalez.plus.com site?

Easy way to tell is to look at the image properties in the browser, if it says
the image is located on the ISP site then you have what you want, if it claims
to be from your own server then you know it wasn't redirected (so probably
proxied).

After changing some settings and restarting Apache don't forget to flush
your browsers cache...its data may prevent the browser from requesting the
image from your server and you will not see a change in the properties of
the image either.

I looked at the image properties in my browser (Mozilla) and it says
that the images come from my own server (2halfs.com). However, i tricked
my webserver into thinking that www.benzalez.plus.com was somewhere else
(edit /etc/hosts), and voila... the graphics still loaded in the
browser. I then tricked my windows/web browser machine into thinking
www.benzalez.plus.com was somewhere else (edit hosts files)... guess
what? graphics couldn't be loaded.

This confirms to me that it's the web browser that is trying to grab the
images of www.benzalez.plus.com, and NOT my webserver :-)

Thanks all
