APM rewriting external URL links

We are using APM to proxy an internal web application.

 

 

The problem is when this website has fully qualified links to websites that are external to the business.

 

 

The links are being rewritten to include the F5's VS name and the path is being manipulated to look like:

 

https://our.virtual.name/f5-w-687474703a2f2f7777772e676f6f676c652e636f6d2e6175$$/

 

 

This causes the client to connect to the F5 and then the F5 attempts to proxy this request to the external site.

 

 

Can understand why this happens with internal application links, but with external links we would like them to be left alone - who can we accomplish this?
