[users@httpd] Mod_proxy and javascript problem
Hello community.
I'm trying to set up a reverse proxy under apache 2.0.54 (debian version).
The server i'm proxy reversing is a IIS 6.0 with class server on it (a
microsoft application for school networking).
I'm using mod_security, rewriterules and proxy for the reverse proxy and some of
virtual hosting because I'm masking 3 IIS server behind a linux/apache
server.
Each server is reached as follow :
http://www.toto.net/ goes to server1 (1.0.2.1)
http://www.toto.net/class goes to server2 (1.0.0.2)
http://www.toto.net/prod goes to server3 (1.0.0.3)
http://www.toto.net/sst goes to stats on the apache server
The big problem is that some javascript (.js) are not correctly interpreted
on the browser, so the html page is broken.
My vhost looks like this :
<VirtualHost *:443>
SSLEngine On
SSLProxyEngine on
SSLCACertificateFile /etc/apache2/ssl/cacert.pem
#SSLCertificateFile /etc/apache2/ssl/www.toto.net.crt

</VirtualHost>
Of course I'm limited in debugging because the class server application needs IE 6.0...
The Html source page is the same if I go directly to the server or if I go through the proxy

I can post the javascript but it's quite long (I will on users demands).
Anyway it's looks like mod_proxy cannot proxy correctly some javascript, maybe
someone can help me ?
thanks
PS: Please, forgive my bad english...
PS2: mod_security does not looks like to be the problem as desactivating it does not change anything

This is probably because the javascript contains links using the
private names/paths rather than the public ones. You can fix this
with mod_proxy_html:
