Warm-Up Script not writing to log file

Question

I have been working on implementing the warm-up script from Ingo Karstein Warm-Up Script

The script runs without any issues, but the log file (.txt) is not being generated as expected. I have the scripts in a directory c:\Tools\Scripts

Answer 1

Set the $filename variable to some other location like "c:\lastrunlog.txt". The log file will be generated with complete output.

Try the updated script below:

#<---- Improvement starts here
#region MyWebClient
Add-Type -ReferencedAssemblies "System.Net" -TypeDefinition @"
using System.Net;

public class MyWebClient : WebClient
{
    private int timeout = 60000;

    public MyWebClient(int timeout)
    {
        this.timeout = timeout;
    }

    public int Timeout
    {
        get
        {
            return timeout;
        }
        set
        {
            timeout = value;
        }
    }

    protected override WebRequest GetWebRequest(System.Uri webUrl)
    {
        WebRequest retVal = base.GetWebRequest(webUrl);
        retVal.Timeout = this.timeout;
        return retVal;
    }
}
