Hey Aaron.

 

 

thanks for the response.

 

 

I'm not sure I'm clear with what you're explaining in regard to the stream config.

 

 

I think I've got the request and response rules correct (but would appreciate your view on this - pls see below for rules) but I think you're suggesting I need to look at creating a stream profile too and then I think using that stream profile in the response iRule, is this correct?

 

 

request irule.

 

when HTTP_REQUEST {

 

if { [HTTP::host] equals "www.mycompany.co.uk"} {

 

HTTP::header replace "Host" "www.provider.com"

 

}

 

}

 

 

response irule.

 

when HTTP_RESPONSE {

 

if { [HTTP::status] starts_with "3" } {

 

HTTP::header replace Location [string map -nocase {www.provider.com www.mycompany.co.uk} [HTTP::header Host]]

 

}

 

}

 

 

thanks,

 

Steve.

    Hello Steve, I'm looking to do something similar. The jist of it is we are trying to mask a external domain name on the front end, but intercept it from the F5 and replace the internal domain name to the back-end server, and when it comes back it preserves the masking external domain.

     

    Did you or anyone do the something similar? Sharing the code snippet is fully appreciated.

     

    Thanks.
