Lowercase URI

Try this one:

when HTTP_REQUEST {
 if { (string match {A-Z} [HTTP::uri]) and ([HTTP::path] ends_with ".aspx")} {
  set hostname [string tolower [HTTP::host]]
  set uriname [string tolower [HTTP::uri]]
  log local0. "Request is $hostname$uriname"
  HTTP::redirect "http://$hostname$uriname" 
 } 
}

01070151:3: Rule [/Common/Set_lowercase2] error: line 2: [parse error: PARSE syntax 34 {syntax error in expression " (string match {A-Z} [HTTP::uri]) and ([HTTP::path] ends_wit...": variable references require preceding $}] [{ (string match {A-Z} [HTTP::uri]) and ([HTTP::path] ends_with ".aspx")}]

Bad formatting on my part:

when HTTP_REQUEST {
 if { [string match {[A-Z]} [HTTP::uri]] and ([HTTP::path] ends_with ".aspx")} {
  set hostname [string tolower [HTTP::host]]
  set uriname [string tolower [HTTP::uri]]
  log local0. "Request is $hostname$uriname"
  HTTP::redirect "http://$hostname$uriname" 
 } 
}

Same result. It isnt redirecting any part of the url to lowercase.

Let's try nested if statements, with logging. This preserves your original check which you say was working:

when HTTP_REQUEST {
 if { [string match {[A-Z]} [HTTP::uri]] } {
  log local0. "Capital letter found in URI"
  if { [HTTP::path] ends_with ".aspx" } {
   set hostname [string tolower [HTTP::host]]
   set uriname [string tolower [HTTP::uri]]
   log local0. "Request is $hostname$uriname"
   HTTP::redirect "http://$hostname$uriname" 
   } 
  }
}

What gets logged to /var/log/ltm when you attempt a connection using this iRule and an FQDN of http://stg.sp10.shrm.org/LegalIssues/EmploymentLawAreas/Pages/default.aspx?

Im not seeing anything in the logs related to that Irule.

Are you certain the FQDN you are using to test with is resolving to the virtual server IP address that you have this iRule applied to? The iRule is now using your original logic which you said was working (simply matching an uppercase letter). If that were the case, then you should at least be seeing the "Capital letter found in URI" message in your LTM log.

Yes Im sure. The only Irule I ever actually had working was the one posted at the very top of this thread

hen HTTP_REQUEST {

HTTP::redirect "http://[HTTP::host][string tolower [HTTP::path]][HTTP::query]" } }

Okay, so path instead of uri was used in your original iRule. Can't imagine that would make a difference, but...

when HTTP_REQUEST {
 if { [string match {[A-Z]} [HTTP::path]] } {
  log local0. "Capital letter found in URI"
  if { [HTTP::path] ends_with ".aspx" } {
   set hostname [string tolower [HTTP::host]]
   set uriname [string tolower [HTTP::uri]]
   log local0. "Request is $hostname$uriname"
   HTTP::redirect "http://$hostname$uriname" 
   } 
  }
}

I dont see anything in the Logs. I do see it execute under the local traffic stats.
