    solved as tcl[HTTP::uri "/ICTDesktop[HTTP::uri]"]

    ps: also tcl[HTTP::path "/ICTDesktop[HTTP::path]"] works

ArlindT This might do what you want, this is also assuming I understood the situation.

when HTTP_REQUEST priority 500 {

    if {[HTTP::host] == "ictservice.it"} {
        if {[[string tolower [HTTP::uri]] == "/some_text/etc"} {
            HTTP::uri [string map {"/some_text/etc" "/ICTDesktop/some_text/etc"}[HTTP::uri]]
            pool POOL_your_pool
        }
    }

}

i was thinking something like that

 

tcl:[
set old_path [HTTP::path]
set new_path /ICTdesktop${old_path}
string map [list "$old_path" "$new_path"] [HTTP::uri]
]

    ArlindT I don't believe this would work well with a string map because a string map works off of a static value being changed to another static value. What is the reason behind having to insert the "/ICTdesktop" into the path? This might be something that is better taken care of on the server side and letting the client see the path rather than attempting to hide it from the client.

      we had this request to balance:

      node1/ICTdesktop

      node2/ICTdesktop

      pool1( node1 + node2) -> policy ictservice.it/variable_path

      the requester want ictservice.it/variable_path

      to be processed as ictservice.it/ICTdesktop/variable_path

       

      you think this is better to be done Server side, or can be done also F5 side?
