Help me with redirect and match cases, please

Well, I got a chance to test the matching cases irules yesterday. All worked well, except when I modified the above irules little bit, the use pool function never worked out right.

 

if (tolower(http_uri contains "logon")) {

 

redirect to "https://" + http_url + tolower(http_uri)

 

}

 

else {

 

use pool my_pool

 

}

 

 

For example: when I typed http://www.secure.com/logon/default.aspx, the irules redirected to secure site https:// and this part worked fine; however, when I removed /logon/default.aspx, the irules didn't redirect to http://, instead it still kept https://. So I think the use pool function never worked in this case.

 

When I configured my_pool, I used http service for all its members.
