Hello Guys,

This is my first query on iRule :slight_smile:

**_My Requirement is : when some body access the http://abc.com/test/test.htm is should get redirected to new server & new URL which is http://pqr.com/test/test.htm.\_\*\*

Note :1) abc.com website is public n locally published

2)website pqr.com is locally published.

Briefing :I want to redirect the user when they try to specifically access from below URI ( /test/test.htm) of the following URL

http://abc.com/test/test.htm the traffic should redirect to new Pool else

For other or any URI as below

http://abc.com/abc1/abc.htm http://abc.com//abc2.abc2.htm

it should go to old Pool

Please suggest if the following steps are correct -

VS = 192.168.1.x is mapped wih public ip on Firewall and published wtih ISP

1)Old Pool = abc-pool -- Remarks for all URI except /test - URI

2)New Pool = pqr-pool ---- Remarks only /test (URI)

Data group (example:Test- Redirect):

“/test” := “pqr-pool”

when HTTP_REQUEST { if { [class match [string tolower [HTTP::uri]] starts_with Test- Redirect] } { pool [class match -value [string tolower [HTTP::uri]] starts_with Test- Redirect] } else { pool abc-pool } }

the irule looks fine for me.

when HTTP_REQUEST { 
  if { [class match [string tolower [HTTP::uri]] starts_with Test-Redirect] } { 
    pool [class match -value [string tolower [HTTP::uri]] starts_with Test-Redirect] 
  } else { 
    pool abc-pool 
  } 
}

Your iRule looks correct.

when HTTP_REQUEST { 
    if { [class match [string tolower [HTTP::uri]] starts_with Test-Redirect] } {
        pool [class match -value [string tolower [HTTP::uri]] starts_with Test-Redirect] 
    } else { 
        pool abc-pool 
    } 
}

** not sure if the space between “Test-” and “Redirect” was intentional, but there cannot be a space in the name. Otherwise, if it’s as simple as a single URI check, you could probably skip the data group lookup.

when HTTP_REQUEST {
    if { [string tolower [HTTP::uri]] starts_with "/test" } {
        pool pqr-pool
    } else {
        pool abc-pool
    }
}

I’d also recommend applying a OneConnect profile here.

Hello Kevin,

Space in Data group (example:Test- Redirect): was a typo error and i will make sure

no space between when i implement the iRule.

Other than this is every thing seems ok in iRule for this requirement.
