New to iRule and need it for this scenario

Question

Hi guys, i need some help regarding the iRule so here's the scenario.

I have a VS named MY_VS

in this VS there are 2 iRules.

iRule1 is at the top and iRule2 is at the bottom.

iRule 1 is to Block HTTP OPTIONS method.

when HTTP_REQUEST {

if { ( [HTTP::method] equals "OPTIONS" ) } {

TCP::close

}

iRule 2 is to redirect request to specific pool based from URI

when HTTP_REQUEST {

if { [string tolower [HTTP::uri]] starts_with "/PAGE1" } {

pool MY_POOL_1

persist cookie insert PAGE1-COOKIE 0

} elseif { [string tolower [HTTP::uri]] starts_with "/PAGE2" } {

pool MY_POOL_2

persist cookie insert PAGE2-COOKIE 0

} elseif { [string tolower [HTTP::uri]] starts_with "/PAGE3" } {

pool MY_POOL_3

persist cookie insert PAGE3-COOKIE 0

} else {

pool MY_DEFAULT_POOL

}

Now The issue:

There is a request that requires HTTP OPTIONS to be forwarded/allowed to PAGE3 URI only.

for All other URI, HTTP OPTIONS must still be blocked.

Thanks for the answers.
