Having trouble with ESI headers

Thank you for the reply. Just so I am clear, this is something that the web server should always set or only when it sees the Surrogate header in the request. I am not using Apache and I cannot tell my web server to add that, so I suspect I may need to use an IRule to do that (depending upon where the request is in the chain).

 

 

I can understand if the request goes to an application as it can set any header it wants, but in a static page generated from the web server file system, I hope that an iRule adding the header is sufficient.

 

 

Thanks,
