iRule to Add Trailing Slash Except for Extensions

Hello,

Considering that the resource will only have the dot char to extensions, I do this way:

when HTTP_REQUEST {
    if { not ( [HTTP::path] ends_with "/") && not ( [URI::basename [HTTP::uri]] contains "." ) } {
        # Append slash and keep querystring when it exists
        HTTP::uri [HTTP::path]/[expr { "[URI::query [HTTP::uri]]" eq {} ? {} : "?[URI::query [HTTP::uri]]" }]
    }
    if { [string tolower [HTTP::uri]] starts_with "/apps" } {
        pool ProxyPass_DEV_pool_2
    }
    else {
        pool ProxyPass_DEV_pool_1
    }
}

Where:

1. "/apps" will become "/apps/" internally;
2. "/apps?param=value" will become "/apps/?param=value" internally;
3. "/test.html" and "/test.html?param=value" remais the same. 

I hope it helps.

Regards
