Hi,
Just see that the class match cause your error. Try this instead :
when CLIENT_ACCEPTED { set allowed 0 if { [whereis [IP::client_addr] country] equals "EG" } { set allowed 1 } } when HTTP_REQUEST { if { ($allowed == 0) and ([HTTP::uri] ends_with "/register") } { HTTP::respond 403 content "Blocked!" } }
ahmed_ismail_21Hi Yann, your help is appreciated, the below iRule didn't work, means when I opening this URL "test.com/register" which end with /register from Egypt, the website didn't redirect me to test.com/register, plus home page of website didn't open as well. when CLIENT_ACCEPTED { set allowed 0 if { ([whereis [IP::client_addr] country] equals "EG") or (![whereis [IP::client_addr] country ] equals "EG") } { set allowed 1 } } when HTTP_REQUEST { if { ($allowed == 0) and ([HTTP::uri] ends_with "/register") } { HTTP::redirect "http://www.test.com/register"} elseif { ($allowed == 1) and ([HTTP::path] ends_with "/register") } { HTTP::redirect "http://www.test/login"} else {pool test} }

Hi,
are the exact opposite.([whereis [IP::client_addr] country] equals "EG") or (![whereis [IP::client_addr] country ] equals "EG")You have to remove one of the condition. Because of possible subsequent requests, I suggest to change a little bit your irule. For example :
when HTTP_REQUEST { set allowed 0 if { !([whereis [IP::client_addr] country ] equals "EG") } { set allowed 1 } if { ($allowed == 0) and ([HTTP::path] ends_with "/register") } { HTTP::redirect "http://www.test.com/register" } elseif { ($allowed == 1) and ([HTTP::path] ends_with "/register") } { HTTP::redirect "http://www.test/login" } else { pool test } }- ahmed_ismail_21Hi Yann, First Thank you, but unfortunately didn't work at all even the main website didn't work, means when I tried to open the main website test.com, which match on pool test didn't open, wrap up, the redirect and main page of website didn't work.

Hi,
Sorry just published a new version, I saw a mistake in the irule :
can't use empty string as operand of "!" while executing "if { (![whereis [IP::client_addr] country ] equals "EG") } { set allowed 1 }"here the irule :
when HTTP_REQUEST { set allowed 0 if { !([whereis [IP::client_addr] country ] equals "EG") } { set allowed 1 } if { ($allowed == 0) and ([HTTP::path] ends_with "/register") } { HTTP::redirect "http://www.test.com/register" } elseif { ($allowed == 1) and ([HTTP::path] ends_with "/register") } { HTTP::redirect "http://www.test.com/login" } else { pool test } }- ahmed_ismail_21Hi Yann, Thank you for your support, now main website is work, but the URL test.com/register which end with /register didn't work, mean the web page didn't open, whatever I open this URL from Egypt or Not.

Just to summarize what the irule do :
- if Country=EG and path=/register then redirect to http://www.test.com/register
- if Country!=EG and path=/register then redirect to http://www.test.com/login
- if path!=/register then go to pool test
What is your exact issue now ?
Where is www.test.com located ?
Is it the same VS or another one ?
- ahmed_ismail_21The redirect didn't work, the www.test.com located at Egypt, the same VS. I made test, I located at Egypt, and change redirect to be http://www.test.com/login, and open url which end with /register, but F5 didn't redirect me to www.test.com/login.
- Yann_Desmarest_You should trace http request/response on your computer using httpwatch or fiddler for example. The provided irule works for me in my lab so I believe that you have another issue on your side

Vijay_Elog local0. "[IP::client_addr] - [whereis [IP::client_addr] country ]"Add a log entry to see what the F5 is seeing:
when HTTP_REQUEST { set allowed 0 if { !([whereis [IP::client_addr] country ] equals "EG") } { log local0. "[IP::client_addr] - [whereis [IP::client_addr] country ]" set allowed 1 } if { ($allowed == 0) and ([HTTP::path] ends_with "/register") } { HTTP::redirect "http://www.test.com/register" } elseif { ($allowed == 1) and ([HTTP::path] ends_with "/register") } { HTTP::redirect "http://www.test.com/login" } else { HTTP::redirect "http://www.test.com/login" } }
