Title: Issue with Proxypass Virtual Servers
Post by: blacktusk on September 29, 2012, 05:02:49 AM

I have an issue with HTML rendering on virtual servers inside our firewall. I have setup a simple Proxypass directive for httpd.conf as below (via expand-templates)

   RewriteEngine on
    RewriteCond %{REQUEST_METHOD} ^(TRACE|TRACK)
    RewriteRule .* - [F]


    ProxyPreserveHost On
   # ProxyHTMLEnable On
    # theses dirs are reverse proxyed to an internal server
    ProxyPass /iis http://10.10.10.113/
    ProxyPassReverse /iis http://10.10.10.113/
    ProxyPass /projects/ http://10.10.10.115/projects/
    ProxyPassReverse /projects/ http://10.10.10.115/projects/
    ProxyPass /ubuntu http://10.10.10.114/
    ProxyPassReverse /ubuntu http://10.10.10.114/

There are 3 virtual servers, identified by /iis, /projects and /ubuntu.

The redirection works fine, however, when I navigate to a page I do not get the correctly rendered HTML, just text content. If I use the back button in the browser then it renders correctly in Internet Explorer, however in Firefox, it never renders correctly.

I have found various information about rewrite directives and EnableHTML, however, any of these I have tried result in the web page bei ng Not found on the server!

Any ideas woul be most welcome. I am running SME Server8 as a VM under ESXI 5.0 running on a DELL R710 Server. Port 80 is redirected to the SME server via our Sonicwall firewall.

Does it work if you use SME's built-in proxypass configuration as described here?
http://wiki.contribs.org/SME_Server:Documentation:FAQ#ProxyPass_a_alias.2Fdirectory.2Flocation

That is:

Code: [Select]

db accounts set iis ProxyPass
db accounts setprop iis Target http://10.10.10.113
db accounts setprop iis Description IIS
db accounts setprop iis HTTP on
db accounts setprop iis HTTPS on
db accounts setprop iis ValidFrom 0.0.0.0/0
expand-template /etc/httpd/conf/httpd.conf
sv t httpd-e-smith

Or, all on one line for each URL:

Code: [Select]

db accounts set iis ProxyPass Target 'http://10.10.10.113/' Description IIS HTTP on HTTPS on ValidFrom '0.0.0.0/0'
db accounts set projects ProxyPass Target 'http://10.10.10.115/projects/' Description Projects HTTP on HTTPS on ValidFrom '0.0.0.0/0'
db accounts set ubuntu ProxyPass Target 'http://10.10.10.114/ Description Ubuntu HTTP on HTTPS on ValidFrom '0.0.0.0/0'
expand-template /etc/httpd/conf/httpd.conf
sv t httpd-e-smith

(Note: I suspect the ValidFrom directive could be left off - it's intention is to allow you to have the proxypass work only from a specific selection of remote IPs)

That would be due to an error on the part of the backend webserver - not setting content-type correctly. If you tell us the name of the website, or websites.
