100s of redirects in policies. How do I get them from 302 to 301

Hi,

If you move to v14, you have the option to set the code in the redirect rule.

In earlier versions, I used to set a tcl variable on policy rule and read then in iRule script.

I don't have a v11.4 screenshot, but it's close to this:

The iRule content:

 

when HTTP_REQUEST {
    if { [info exists redirect301] } {
        HTTP::respond 301 -version auto noserver Location $redirect301 Connection close
        unset redirect301
    }
}

 

If you decide to change it before move to v14, to replace hundred of rules, you can list policies and run a script or manually edit then to merge it on command line:

e.g.

 

tmsh list ltm policy my_policy  |awk '{ sub(/http-reply$/,"tcl") sub(/redirect$/,"set-variable name redirect301") sub(/location(.*)$/,"expression " $2) }1'

 

Original content / before to be edited:

 

ltm policy my_policy {
    controls { forwarding }
    requires { http }
    rules {
        rule1 {
            actions {
                0 {
                    http-reply
                    redirect
                    location https://www.mydomain.net[HTTP::uri]
                }
            }
            ordinal 1
        }
    }
    strategy first-match
}

 

After run command / edit:

 

ltm policy my_policy {
    controls { forwarding }
    requires { http }
    rules {
        rule1 {
            actions {
                0 {
                    tcl
                    set-variable name redirect301
                    expression https://www.mydomain.net[HTTP::uri]
                }
            }
            ordinal 1
        }
    }
    strategy first-match
}

 

You must check if all rules are right, OK? 🙂

Then, you can save it on file (e.g. myfile.conf) to merge on command line or read from terminal.

See:

Make sure it's all OK with "verify" statement:

e.g.

# tmsh load sys config merge file /var/tmp/myfile.conf verify

When all it's OK, merge it:

# tmsh load sys config merge file /var/tmp/myfile.conf

Please, run a backup before make changes.

I hope it helps.
