Confusing (well to me!) Profile issue

The experience I have had using the Redirect Rewrite was for consistency.

 

 

We had a pair of VIPs:

 

Port 80 - iRule for HTTP to HTTPS Redirect.

 

Port 443 - SSL Offload

 

 

On the HTTPS VIP we were doing SSL Off-Load and communicated to the backend server via HTTP. As far as the client was concerned all of the communication was HTTPS, but the application believing that it was HTTP would give all redirects in HTTP.

 

 

Using the Redirect Rewrite "Matching" setting caused the VIP to look at all redirects and change them all to HTTPS.

 

 

Client accesses the site:

 

HTTPS://www.website.com

 

 

Server sents redirect for content:

 

HTTP://www.website/somecontent/index.html

 

 

F5 (Matching Setting) captures the redirect traffic and compares the original URL (HTTPS) and the redirect URL (HTTP) and forces a consistency by changing the redirect HTTPS://www.website/somecontent/index.html

 

 

This is how we are using it in one instance on one setting. I haven't had the time to test any other uses for it or come across any other situations that might need it.
