NimbostratusiRule redirect to HTTPS - Logical Error
Hi,
I have a logical error in my iRule. We only want to encrypt specific URLs. We have a site that hosts multiple applications.
Part One: http://websiteROOT/websiteA - websiteE redirect to their HTTP pool, success
Part Two: http://websiteROOT/websiteF, since it is not defined in the iRule redirects to HTTPS, success
Part Three: We want http://websiteROOT to redirect to HTTPS as well, failed
when HTTP_REQUEST {
if {[ string tolower [HTTP::uri]] starts_with "/websiteA" } {
pool pool_websiteA
} elseif {[ string tolower [HTTP::uri]] starts_with "/websiteB" } {
pool pool_websiteB
} elseif {[ string tolower [HTTP::uri]] starts_with "/websiteC" } {
pool pool_websiteC
} elseif {[ string tolower [HTTP::uri]] starts_with "/websiteD" } {
pool pool_websiteD
} elseif {[ string tolower [HTTP::uri]] starts_with "/websiteE" } {
pool pool_websiteE
} elseif {[ string tolower [HTTP::host]] equals "websiteROOT" } {
HTTP::redirect "https://[HTTP::host][HTTP::uri]"
} else {HTTP::redirect "https://[HTTP::host][HTTP::uri]"}
}
Well, that elseif as it's currently written will never match because you're converting the host to lowercase and then attempting to match it against a string with upper case characters (websiteROOT). I realize this is a sanitized iRule, but I just wanted to raise this point in case that is your issue. Try this one:
when HTTP_REQUEST { if { [string tolower [HTTP::uri]] starts_with "/websiteA" } { pool pool_websiteA } elseif { [string tolower [HTTP::uri]] starts_with "/websiteB" } { pool pool_websiteB } elseif { [string tolower [HTTP::uri]] starts_with "/websiteC" } { pool pool_websiteC } elseif { [string tolower [HTTP::uri]] starts_with "/websiteD" } { pool pool_websiteD } elseif { [string tolower [HTTP::uri]] starts_with "/websiteE" } { pool pool_websiteE } else { HTTP::redirect "https://[HTTP::host][HTTP::uri]" } }

It seems like your elseif looking for websiteROOT isn't necessary. The final else statement should catch it and redirect to HTTPS.
You only have this iRule applied to your port 80 virtual server, correct?
Nfordhk_66801I completely agree with you, but it wasn't working so I tried to add it in to specify it. That is correct, it is applied to the HTTP server.

Yes, I realize it must match. My original iRule is all lowercase when defining the strings. If i'm viewing this correctly you just chopped out the last elseif? I tried removing it but, it didn't redirect the root url still.
- Nfordhk_66801Working now! Work's great in firefox just not IE. But that's a different issues. I've been having issues with my IE with various sites. Thanks!
- Cory_50405You got it. Glad to hear it's working.
