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
