ProxyPass being used but 'some' images not displaying properly

Hello all,

 

 

I am using the ProxyPass irule, redirecting users to an external site when they go to a specific URI, hiding this from the user.

 

This all works however some of the images on the external website do not display correctly (the internal site is fine).

 

 

Has anyone goy any idea why this might be the case and how to resolve?

 

When navigating directly to the website all the images display correctly (all .jpg).

 

The issue only occurs to certain images.

 

The external site is targeted over ssl so a server ssl profile is used.

 

 

Many thanks in advance.
