What would cause this rule to fail. I don't see anything wrong.

The reason why it's failing is because "HTTP::retry" is only valid for the following events : HTTP_RESPONSE, HTTP_RESPONSE_DATA. It doesn't work under LB_FAILED event. - Thanks. On a side note, someone needs to fix the code example under LB::reselect

One piece of warning with HTTP::retry
If you try to re send a POST request it won't work. you'll lose the payload with the parameters :'(- Nicolas_Menantsort of ^^
