PowerShell v3 Function Test Uri

As part of the security module I am working on I thought some Uri testing would be a good analysis tool. This function is merely a subroutine, but, still is worth pointing out:

function Test-Uri

{

      <#

            .EXAMPLE

                  Test-Uri -Uri http://www.msn.com

                  True

           

            .EXAMPLE

                  Test-Uri -Uri http:/hax0r.com

                  False

      #>

     

      param(

            [ValidateNotNullOrEmpty()]

            [String]

            $Uri 

      )

     

      if([System.Uri]::IsWellFormedUriString($Uri, [System.UriKind]::RelativeOrAbsolute))

      {

            [System.Uri]::TryCreate($Uri, [System.UriKind]::RelativeOrAbsolute, [ref] $uri)

      }

      else

      {

            $false

      }

}

The two key lines here are the  IsWellFormedUriString and  TryCreate . You can get more details about how these work from MSDN.

• IsWellFormedUriString:  Uri.IsWellFormedUriString Method
• TryCreate:  Uri.TryCreate Method (String, UriKind, Uri%)

Again, this is a simple function, but, highly useful for anyone doing pen testing, analysis, checks, etc.
