Updating base href on Plone 4

Hello! I am new to the Plone forms. So please let me know if I am posting to the wrong location.

I cloned a virtual machine running plone 4 to do some development work. I have the new vm running plone now. The problem I am facing is that my development plone instance is inserting the following into each header:

< base href="http://production.web.site/" / >

Where is this set? Is there anyway to override this in the build out scripts? Or is there some other way to change this?

Thanks for your help,
Aaron

If you use a reverse proxy like Apache or Nginx, you have to change the rewrite rules for the virtual hosting.

Aj, you are right. I updated apache, but I missed two lines which set the host for the proxypass.

Thanks!
