Hi Rakesh,

you may take the snippet below as a starting point...

when HTTP_REQUEST {
    if { ( [string tolower [HTTP::host]] eq "sfobjtest.govnet.nsw.gov.au" )
     and ( [string tolower [HTTP::path]] starts_with "/id:" ) } then {
        HTTP::respond 307 Location "https://sfobjtest.govnet.nsw.gov.au:8443//documents/[findstr [HTTP::path] "/id:" 4 "/"]"
    }
}

The iRule uses a 

[findstr [HTTP::path] "/id:" 4 "/"]
syntax to parse the 
[HTTP::path]
for the first ocourence of the string 
/id:
, then skip 4 bytes (aka. 
/id:
is skipped) and then take the remaining 
[HTTP::path]
till the next ocourence of 
/
.

Note: If the iRule does not work out for you, then please reply with Real-World examples of the two URLs formats that need to become redirected...

Cheers, Kai
