PowerShell Requires Chilkat v11.0.0+

Get Size of File on Web Server

See more HTTP Examples

Demonstrates how to send a HEAD request to fetch information about a file on a web server, which hopefully includes the Content-Length in the response header. PowerShell

Add-Type -Path "C:\chilkat\ChilkatDotNet47-x64\ChilkatDotNet47.dll"

$success = $false

#  This example assumes the Chilkat API to have been previously unlocked.
#  See Global Unlock Sample for sample code.

$http = New-Object Chilkat.Http

$resp = New-Object Chilkat.HttpResponse
$success = $http.HttpNoBody("HEAD","https://nodejs.org/dist/v10.16.1/node-v10.16.1-win-x64.zip",$resp)
if ($success -eq $false) {
    $($http.LastErrorText)
    exit
}

#  Examine the response header.
$($resp.Header)

#  Here is a sample response header:

#  Date: Thu, 01 Aug 2019 12:47:27 GMT
#  Content-Type: application/zip
#  Content-Length: 17457922
#  Connection: keep-alive
