How can I detect # sign in URI using irule

I'd like to distinguish between the following two URLs

 

 

1) https://host.com/abc/ux/flash.html

 

 

2) https://host.com/abc/ux/flash.htmltab=Home%28page=Home&id=h4rih9ki%28%29%29

 

 

 

 

 

 

The difference between these two URLs is the existence of and some characters.

 

 

 

The set uri [] has the same value for both the above URLs. Is there a different header attribute or something that I can use to detect this ?

    Might not be the most graceful solution, but using "contains" works. I threw this onto a dev F5 and tested-- seems to work.

     

     

    if {[HTTP::uri] contains ""} { log local0. "Found " } else { log local0. "No " }

     

     

    You could also just grab everything after the first using the following:

     

    set vars [getfield [HTTP::uri] "" 2]

     

     

    Hope this is atleast somewhat helpful.

    is it fragment identifier?

     

     

    i thought it is client-side only i.e. browser does not send it to server (bigip).

    As Nitass said, the user-agent shouldn't include the anchor (or fragment) in its request to the web server--it's just by the server to tell the client how to render the page and/or focus the page once it is loaded.
