PowerShell script to check the status of a URL

Question

Similar to this question here I am trying to monitor if a set of website links are up and running or not responding. I have found the same PowerShell script over the Internet. However, instead of direct website links I need to check more specific links, for example: ``` http://mypage.global/Chemical/ http://maypage2:9080/portal/site/hotpot/ ``` When I am trying to check on the status of these links, I get the following output: ``` URL StatusCode StatusDescription ResponseLength TimeTaken http://mypage.global/Chemical/ 0 http://maypage2:9080/portal/site/hotpot/ 0 ``` The above links requires me to be connected to the VPN, but I can access these links from the browser. Output of `Invoke-WebRequest -Uri https://stackoverflow.com/questions/20259251/powershell-script-to-check-the-status-of-a-url`: ``` PS C:\Users\682126> Invoke-WebRequest -Uri https://stackoverflow.com/questions/20259251/powershell-script-to-check-the-status-of-a-url The term 'Invoke-WebRequest' is not recognized as the na…

I recently set up a script that does this.

As David Brabant pointed out, you can use the `System.Net.WebRequest` class to do an HTTP request.

To check whether it is operational, you should use the following example code:

```
# First we create the request.
$HTTP_Request = [System.Net.WebRequest]::Create('http://google.com')

# We then get a response from the site.
$HTTP_Response = $HTTP_Request.GetResponse()

# We then get the HTTP code as an integer.
$HTTP_Status = [int]$HTTP_Response.StatusCode

If ($HTTP_Status -eq 200) {
    Write-Host "Site is OK!"
}
Else {
    Write-Host "The Site may be down, please check!"
}

# Finally, we clean up the http request by closing it.
If ($HTTP_Response -eq $null) { } 
Else { $HTTP_Response.Close() }
```
