Hi,     I am working with an iRule provided by System Engineer at F5. The iRule was designed to give us the same information our custom apache log gives us (we are moving from Apace to F5).  ...

[HTTP::header exists HEADER_NAME] will return 1 if the header HEADER_NAME has a value set and 0 if the header doesn't have a value. To get the actual value, you can use [HTTP::header value HEADER_NAME]. If the header isn't set, I think the command will return a null string. So you could just use 'value' instead of 'exists'.
