[URGENT] - Need help on Irule for URL/URI redirect

Sarovani

We want all the request comming to www.example.fr from specific source 10.10.10.1 to get redirected to www.example.fr/ckpartner/ and this should be logged . 

 

 

 

 

Can you please with the below Irule we can achieve this ? Or any modification is required for this .

 

 

 

when HTTP_REQUEST {

 

if { ([IP::addr [IP::client_addr] equals 10.10.10.1]) && ([HTTP::host] starts_with "www.example.fr") } {

 

log local0.

 

set newUri [string map {"/" "ckpartner/"} [HTTP::uri]]

 

HTTP::uri $newUri

 

}

 

}

You can try something like this:

when HTTP_REQUEST { if { ([HTTP::host] equals "www.example.fr") } { HTTP::redirect "www.example.fr/ckpartner" log local0. "Client IP [IP::client_addr] has been redirected" } }

 

Thanks Rodrigo ,

 

This Irule should only redirect when external users are trying to access the VIP , So we don't want this to impact the internal clients ...So we want to redirect only when we see request from specific external clients .

Then you can use a class match function along with a data group to define your external IP ranges you want redirected.

 

Something like this:

when HTTP_REQUEST { if { ([HTTP::host] equals "www.example.fr") and [class match [IP::client_addr] equals "specific_external_client_range_data_group"] } { HTTP::redirect "www.example.fr/ckpartner" log local0. "Client IP [IP::client_addr] has been redirected" } }

To create a data group you can use tmsh create /ltm data-group...

 

I'd also advise you to look into LTM policies as they might be more efficient.

 

Please, test it first 🙂

Thanks for your help ,

 

My requirement is currently working with below Irule but I would like to add Datagroup to below Irule so that I can filter more external IP's

Could you please help me modify this irule .

I tried but I got error "variable reference required preeciding $"

 

 

 

when HTTP_REQUEST {

if {

                 ([IP::client_addr] contains "10.10.10.1%70") && ([string tolower [HTTP::uri]] contains "/cklauncher/")

                                  }

                                               {

                drop

}                                                             

elseif { [string tolower [HTTP::path]] equals "/" && ( [IP::addr [IP::client_addr] equals 10.10.10.1%70]) } {

# redirect the request

log local0. "issuing redirect request to [HTTP::host][HTTP::uri] from [IP::client_addr]"

HTTP::redirect https://[getfield [HTTP::host] ":" 1]/ckpartner/

}

}
