Traffic redirection

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

Hi Kai,

 

I applied the irule but it doesn't seem to work.

 

Just this simple redirection rule doesn't work:-

 

when HTTP_REQUEST {

 

if { [string tolower [HTTP::host]] equals "sfobjtest.govnet.nsw.gov.au" } {

 

HTTP::respond 301 Location "sfobjtest.govnet.nsw.gov.au:8443//documents" } }

 

The URL ";

 

doesn't redirects to

 

";

 

Please help if possible

 

Hi Rakesh,

if the iRule above does not work at all, then I would recommend to include some Debug-Log line to make sure the iRule gets executed...

when HTTP_REQUEST {
    log local0.debug "Debug: iRule executed"
    if { [string tolower [HTTP::host]] equals "sfobjtest.govnet.nsw.gov.au" } {
        log local0.debug "Debug: [string tolower [HTTP::host]] is matching the pattern"
        HTTP::respond 301 Location "sfobjtest.govnet.nsw.gov.au:8443//documents"
    } else {
        log local0.debug "Debug: [string tolower [HTTP::host]] is not matching the pattern"
    }
}

Note: Keep in mind, that almost every configuration change requires you to close any existing TCP-session. So better close/open your browser between the individual tests to get sure...

Cheers, Kai
