NimbostratusFilter Mulitple Http Requests to Serveral Pools
I need an irule to filter traffic to send it to the correct pool (total of 3 pools) based on the URL. I have a start but need help with this irule.
when HTTP_REQUEST {
if { [HTTP::uri] contains "www.company.com" } {
pool company
}
}
when HTTP_REQUEST {
if { [HTTP::uri] contains "www.company.com/A" } {
pool company.net
}
}
when HTTP_REQUEST {
if { [HTTP::uri] contains "www.company/B" } {
pool company.com
} else {
pool company.com
}
}

- There are a couple of issues here.
First, you have three HTTP_REQUEST events in your rule. Consolidate all your logic into a single when statement.
Second, here's the breakdown for a url
http://www.foo.com/bar
http://[HTTP::host][HTTP::uri]
In this case [HTTP::host] would be "www.foo.com"
and [HTTP::uri] would be "/bar".
You are comparing the URI (HTTP::uri) to both the HTTP::host and HTTP::uri.
You can either rearrange your logic to compare both the host and uri with a logical "and" or break it down into multiple if/elses. Or, if you want to be a real geek, go for a switch statement (search the forums for switch examples). If you get stuck, either search the forums or browse the CodeShare section of the iRules Wiki, there are a bunch of examples in there of exactly this functionality.
