F5 Policy using replace with TCL

[ArlindT]

Hi,

i'm trying to to the following job:

when someone try to browse to ictservice.it/some_text/etc

i want the policy to add the string ICTDesktop int the path -> ictservice.it/ICTDesktop/some_text/etc

and only after forward the traffic to the Pool.

Possibly 'ICTDesktop' to be hiden

How can i do this without irule, but using only TCL or also without TCL?

thanks

Arlind

@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
        }
    }

}

thanks for the support,

the challenging thing is this: some_text/etc is a random part, i don't know it before.

I want something like this:

tcl:[string map {random_uri "/ICTdesktop"+random_uri} [HTTP::uri]]

so it adds /ICTdesktop before the random_uri with a tcl implementation.

[ArlindT]

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.

[ArlindT]

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?

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

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