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

Question

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!

Answer 1

Use WebRequest.Create to create a new HttpWebRequest object and request the web page.

Answer 2

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.

Answer 3

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..."

If the url is on internet, you can also use www.weetasks.com to call any url in 5 minutes interval.
