irule based on URI to select pool redirected back to http

For your iRule, which looks ok but the following is a little improved:

when HTTP_REQUEST {

    if {[string tolower [HTTP::host]] starts_with "test.abc.com"}{

        if {([string tolower [HTTP::uri]] starts_with "/testing") }{
            HTTP::respond 301 Location "https://[getfield [HTTP::host] : 1]/homepage"
        } elseif { [string tolower [HTTP::uri]] starts_with "/homepage" }{
            pool "poolB"
        }
    }
}

If your web server is then doing a redirect it maybe using

http

protocol instead of

https

as the server is listening on HTTP. Should be able to change this setting on the web server so the Location in any redirect HTTP response uses

https

as the protocol or you could write an iRule to change the Location value in any response.

The following iRules is an example of performing this

Location

header replacement:

when HTTP_RESPONSE {

    if {([HTTP::header exists "Location"]) && ([HTTP::header value "Location"] starts_with "http://test.abc.com"))} {
        HTTP::header replace "Location" [string map "http://test.abc.com" "https://test.abc.com" [HTTP::header value "Location"]]
    }
}
