Https redirect and pool selection

I need to write an irule doing two things :

1 - offload SSL and redirect http requests to https

2 - make a pool selection based on the object type requested

ex : for *.php --> send to pool php_pool

for * --> pool to static_pool

so it should look to something like :

http-->https

when HTTP_REQUEST {

HTTP::redirect https://[HTTP::host][HTTP::uri]

}

dispatch requests

when HTTP_REQUEST priority 501 {

switch -glob [HTTP::path] {

*.php { pool php_pool }

default { pool static_pool }

}

}

The problem : it looks like the dispatching section is never processed ! whats wrong with this code ?

Thanks for all

Hamid
