Recommended method for loading a URL via a scheduled task on Windows

Viewed 72123

I have a webpage hosted on a Windows box that I need to assure gets loaded at least once/day. My current plan is to create a scheduled task that opens Internet Explorer and hits the URL:

"C:\Program Files\Internet Explorer\iexplore.exe" myurl.com/script_to_run_daily.aspx

This was simple to setup and works fine, but it strikes me as a hack because Internet Explorer actually has to open and hit this URL. I don't need any input back from this page, it simply stores cached data in files when it's hit.

Is there a slicker way of doing this? In case it matters, this is a VB.net site.

Thanks in advance!

You can schedule a PowerShell script. PS is pretty powerfull and gives you access to the entire .Net Framework, plus change. Here is an example:

$request = [System.Net.WebRequest]::Create("http://www.example.com")
$response = $request.GetResponse()
$response.Close()

Another option is VB Script. For example (save as file.vbs):

sSrcUrl = "http://yourdomain.com/yourfile.aspx"
sDestFolder = "C:\yourfolder\"
sImageFile = "filename.txt"
set oHTTP = WScript.CreateObject("MSXML2.ServerXMLHTTP")
oHTTP.open "GET", sSrcUrl, False
oHTTP.send ""
set oStream = createobject("adodb.stream")
Const adTypeBinary = 1
Const adSaveCreateOverWrite = 2
oStream.type = adTypeBinary
oStream.open
oStream.write oHTTP.responseBody
oStream.savetofile sDestFolder & sImageFile, adSaveCreateOverWrite
set oStream = nothing
set oHTTP = nothing
WScript.Echo "Done..."

As of PowerShell 5.0, curl is an alias for Invoke-WebRequest, so you can create a Scheduled Task as follows:

Action: Start a program
Program/script: powershell
Add arguments: curl http://www.example.com/foo/bar

You can also use Invoke-WebRequest, but curl is more concise.

There are Windows versions of the most common command-line http request tools, such as cURL and wget. You could certainly create a scheduled task that would run one of these. I have also done this from within a Windows Scripting Host script, if you needed to loop or create URL parameters on the fly, or some such.

tried with curl on PowerShell 4.0, curl is an alias for Invoke-WebRequest, so you can create a Scheduled Task as follows:

Action: Start a program Program/script: powershell Add arguments: curl http://www.example.com/foo/bar

worked like a charm!

If you are getting "The underlying connection was closed: An unexpected error occurred on a send" message while running your PowerShell script then add the following line of code to the top of your script:

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

With the latest support of TLS 1.2 and deprecation of TLS 1.0, 1.1 etc., your PowerShell scripts need this necessary change.
