Header Inserts

I am experiencing a somewhat odd situation. I created an HTTP profile and setup a name value pair in the Request Header Insert (SSL_ENV:On). When I debug in Fiddler to see if the header is inserted, I...

when HTTP_REQUEST {
   if { [HTTP::header "HTTP_SSL_ENV"] equals "On" } {
      log local0. "HEADER HTTPS is: [HTTP::header "HTTP_SSL_ENV"]"
   }
}

 

 

Maybe I'm a bit confused now, but why are you looking for the header "HTTP_SSL_ENV" in the iRule?

 

 

The log statements tells me that the HTTP header "HTTP_SSL_ENV" was set, not "SSL_ENV" (see iRule above)!

However, you should set the HTTP header to "SSL_ENV" in the iRule (or profile) on the F5, not "HTTP_SSL_ENV"!. ASP is just using a kind of translation machanism to view the HTTP headers as "variables". They do so by adding HTTP_ in front of the real HTTP header name.

 

 

So, on the F5 please add the header "SSL_ENV" and in your ASP code look for the variable "HTTP_SSL_ENV". Is this what you tried and still did not see the header value in your ASP code?

 

 

BTW: What do you mean by "If I set it as a String and dump the output it works"? Where do you set "it" as a string?
