HTTP Respond Data replacing ?

Hello, chbhatt & tarsier

 

 

I'm trying to find a way with an iRule (or any functionality really) to take a url like

 

https://blo.client.com/rk

 

https://blo.client.com/rk-admin/

 

and convert it to

 

https://blo.server.com/rk/index.htm

 

https://blo.server.com/rk/login.htm

 

 

as it goes through the bigip (running v9).

 

The catch is we cannot redirect the browser client to the blo.server.com/rk/index.htm site, the end user must always see blo.client.com.

 

To make it even more complicated, sometimes the server will send back a payload with a URL inside it for the user that we need to change from blo.server.com to blo.client.com .

 

 

when HTTP_REQUEST {

 

log local0. "[IP::client_addr]:[TCP::client_port]: New request to [HTTP::host][HTTP::uri]"

 

switch "[string tolower [HTTP::host][HTTP::uri]]" {

 

"blo.client.com.ch/rk-admin/" {

 

HTTP::header replace "Host" "blo.server.com"

 

HTTP::uri "/rk/login.htm"

 

set target_pool "blo.server"

 

pool blo.server

 

log local0. "[IP::client_addr]:[TCP::client_port]: [HTTP::host] [HTTP::uri] Rewrite host/uri (1)"

 

}

 

"blo.client.com/rk/" {

 

HTTP::header replace "Host" "blo.server.com"

 

HTTP::uri "/rk/index.htm"

 

set target_pool "blo.server"

 

pool blo.server

 

log local0. "[IP::client_addr]:[TCP::client_port]: Rewrite host/uri (2)"

 

 

}

 

}

 

}

 

when HTTP_RESPONSE {

 

HTTP::collect [HTTP::header Content-Length]

 

if { $target_pool == "blo.server" } {

 

set location [HTTP::header value Location]

 

log local0.info "Server-RESPONS"

 

HTTP::header replace Location [string map -nocase {"blo.client.com" "blo.serve.com"} [HTTP::header Location]]

 

log "BEFORE Replacing payload with new data."

 

}

 

}

 

when HTTP_RESPONSE_DATA {

 

set clen [string length [HTTP::payload]]

 

regsub -all "blo.client.com" [HTTP::payload] "blo.server.com" newdata

 

log "Replacing payload with new data."

 

HTTP::payload replace 0 $clen $newdata

 

HTTP::release

 

}

 

 

 

if is the backend server http (cleartext) this irull is running well, but when I try to change httpS- httpS respond HTTP_response_data it does not function.

 

Is there a way to do this?

 

 

Thanks for any help.
