remove trailing periods

We are receiving a number of users trying to access our webpages but they put a trailing period in the URL e.g.:

 

'http://www.thesite.com./Default.aspx'

 

Note the '.com.'

 

How can I remove the trailing period so that the headers match?

 

i.e. URL should be:

 

'http://www.thesite.com/Default.aspx'
application delivery
dev
devops

    It seems a bit strange that users would add a trailing period, but...

    To remove a trailing period if there is one, you can use 'string trimright', like this:

    
when HTTP_REQUEST {
   if { [HTTP_HOST ends_with "." }{
      HTTP::host [string trimright [HTTP::host] "."]
   }
}

    To test this with logging, you can use this:

    
when HTTP_REQUEST {
   if { [HTTP_HOST ends_with "." }{
      set host_original [HTTP::host]
      set host_trimmed [string trimright [HTTP::host] "."]
      log local0. "\$host_original: $host_original"
      log local0. "\$host_trimmed: $host_trimmed"
      HTTP::host [string trimright $host_original "."]
   }
}

    For details on the string command, you can check the TCL man page for string (Click here).

    Many thanks.

     

    As usual, the guy who got the training has moved on and I have inherited the work :-)

     

    I really appreciate the response
