CirrusURL redirtion not happning through Irule.
Hi All,
I am using simple Irule to redirect Url.
when HTTP_REQUEST { if { [string tolower [HTTP::host]] equals "abc.com" } { HTTP::redirect "https://abc.com/welcome/do" } }
i attached this i rule to standard Virtual server for port 80. HTTP profile is enabled.
But at the time of testing URL redirection not happening....page opening without redirection i.e abc.com.
Please help what i am missing...?

can you do some debugging?

If you use multiple iRules, another possible cause would be a TCL error (e.g. due to multiple redirect invocations). Take a brief look at the /var/log/ltm file as you initiate a connection. If this happens to be the case, use the
command after each redirect statement to ensure no more than one BigIP redirect will be invoked per request.event disable

Good point, but wouldn't `event disable` risk disabling other (required) functionality? I usually implement a semaphore to prevent multiple responses.

giltjrDepending on how your F5 is setup, wouldn't this cause a endless loop? You are only checking for the host name of abc.com and then redirecting to a specific URI at abc.com (https://abc.com/welcome/do).
I would think you may want to check for the URI just equal to "/" and the host name abc.com.

Something else you may want to consider (not related to the problem) is using a 301 instead of a 302.
Instead of
HTTP::redirect "https://abc.com/welcome/do"I would recommend
HTTP::respond 301 Location "https://abc.com/welcome/do"
