[users@httpd] Mod-Proxy
Hello,
I am trying to setup a reverse proxy to one of our applications, but I am
finding that the page comes up, but all the urls that load the stylesheets
and javascript are all broken.
I have pasted below my configuration. Any thoughts on what I am doing wrong
or overlooked?
<Location "/app/">
ProxyPass http://172.17.2.113:2525/
ProxyHTMLEnable On
ProxyHTMLURLMap / /app/
RequestHeader unset Accept-Encoding
</Location>
Thanks for your help

Coincidentally, I've been researching reverse proxy and found this:
http://www.apachetutor.org/admin/reverseproxies#d8
It looks like you have to do some extra work to write rules that match
and rewrite all the urls throughout the html, css, javascript, etc.
When I build a web application, I am very, very careful to write all
urls so that the application can be moved from one server to another
without breaking. I use an approach I call "dynamic absolute" where
the application dynamically detects its location in the file system
and defines that as a constant for the rest of the application to use,
then determines the proper http/https url, defining that as a constant
as well. Then throughout the application, I use the constants, rather
than literally typed url. The end result is absolute urls.
If you didn't have any part in building the application, I apologize.
I consider problems with urls to be a "code smell", specifically
"Excessive use of literals" (http://en.wikipedia.org/wiki/Code_smell).
Usually, where there is one code smell likely to be many more. So
watch out and good luck!
