Hello! Thank you for the swift response...

 

 

1) Presently, you are redirecting based on request URI yes?

 

 

Yes - if the request URI ends with an image extension, it will redirect

 

 

2) You'd rather rewrite responses to avoid the redirect yes?

 

 

Yes - unless I can find some confirmation all browsers (including mobile browsers) will follow redirect requests for images.. I have not been able to confirm nor deny this

 

 

3) Is there a direct correlation between the request URI and the CDN URI? So would www.site.com/images/test.jpg be located at cdn.site.com/images/test.jpg? If not, this is going to be a very long iRule =]

 

 

Yes, it is literally www.site.com/blah.jpg == cdn.site.com/blah.jpg, so on and so forth.

 

 

The CDN provider uses a cname (cdn.site.com) and just correlates that to an origin source which has images in the exact same path.
