Question

I need some help with a basic PowerShell script that sends a 200 HTTP request to a website to check if it's online. I have a script that checks one website, but I need to update it in order to check multiple websites every time it runs. I need to check 8-10 websites at a time.

Thanks.

Here is my script so far:

$HTTP_Request = [System.Net.WebRequest]::Create('http://google.com')

$HTTP_Response = $HTTP_Request.GetResponse()

$HTTP_Status = [int]$HTTP_Response.StatusCode

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

If ($HTTP_Response -eq $null) { } 
Else { $HTTP_Response.Close() }

I tried a few things. Added another HTTP_Request line, added another set of parentheses with the URL. I'm a complete novice when it comes to PowerShell, so any assistance would be greatly appreciated.

My approach would be to create an array of addresses and then loop through them. I'm not great with powershell syntax but something like...

    $websites = @("www.google.com", "www.facebook.com", "www.amazon.com", "www.microsoft.com")

foreach ($site in $websites) {
    Test-Connection $site -Count 1 -Quiet
    if ($?) {
        Write-Host "$site is up"
    } else {
        Write-Host "$site is down"
    }
}
