Irule ending with trailing slash

I have requirement that If URL is referring to a page that does not end with a "/" then redirect to the same URL ending with a "/" but it should not include below points:

1. ignore all request with Method POST

2. ignore all URLs starting with:

/WebResource.axd

/EPiServer.Forms/

 

3. URLs containing :

a query in the URL (indication is “?”)

URLs containing: /api/

    Perhaps something like this:

    when HTTP_REQUEST {
    if { not ( [HTTP::uri] ends_with "/" ) && \
        not ( [HTTP::method] eq "POST" ) && \
        not ( [HTTP::uri] starts_with "/Webresources.axd" ) && \
        not ( [HTTP::uri] starts_with "/EPiServer.Forms/" ) && \
        not ( [HTTP::uri] contains "?" ) && \
        not ( [HTTP::uri] contains "/api/" ) } {
            HTTP::redirect "https://[HTTP::host][HTTP::uri]/"
    } 
}

      Hi Kevin, 

      Thnk you very much for your reply. We have also created below irule ( with one more requirment --- If any letter in the URL contains upper case then redirect to a strict lower case version of the same URL):

      when HTTP_REQUEST {

      if { [HTTP::uri] ne [string tolower [HTTP::uri]] } { HTTP::respond 301 noserver Location [string tolower [HTTP::uri]] }

      if { not ( [HTTP::uri] ends_with "/" ) and ! ([class match [string tolower [HTTP::path]] ends_with /DMZ/extensions]) and (! ([HTTP::uri] contains "/api/") or ! ([HTTP::uri] contains "/WebResource.axd") or !([HTTP::uri] contains "/EPiServer.Forms/") or !([HTTP::uri] contains "?") )} { HTTP::respond 307 Location "[HTTP::uri]/" }
      }

      In this irule we want to ignore all post method request which should not redirect, so let us know how we can achive this condition.

        HTTP::redirect "https://[HTTP::host][string tolower [HTTP::uri]]"
        
    } elseif { not ( [HTTP::uri] ends_with "/" ) && \
        not ( [HTTP::method] eq "POST" ) && \
        not ( [HTTP::uri] starts_with "/Webresources.axd" ) && \

        not ( [HTTP::uri] contains "/api/" ) } {
            HTTP::redirect "https://[HTTP::host][HTTP::uri]/"
    } 
}
