[users@httpd] Reverse Proxy configuration

[Owen Williams]

Hello,
  I am trying to create a reverse proxy to relabel a cloud based service
to look internal to our university.

I'm using:

httpd-2.2.15

I have lots working but I have three examples that where Apache won't
replace text for another URL stub:

1. <script type="text/javascript">
                var PRISM = {
                        'base_url':'http://external.co.uk',

2. <script type="text/javascript"
  src="//external.co.uk/dmu-sandbox/assets/-/tour.en-gb.js"></script>

3. <a 
href="/sessions?saml=1&amp;referer=https%3A%2F%2Fexternal.co.uk%2Fdmu-sandbox%2Faccount"
 

where I want Apache to replace external.co.uk or
external.co.uk/dmu-sandbox with our site or '/'.

Any ideas, please?

Best regards,

Owen.
