ASP Script to check if a web site is up

Bard

Would anyone know a handy asp script for checking if a site is up or not?
For example, I'd like to be able to check if a particular URL is up and active before grabbing data from it or providing a link to it.

Any suggestions?

(ASP only please)

have a look at:
http://www.aspin.com/home/components/internet/pingfunc

You basically want to do a ping on a hostname and depending on the response take action (or not)

If it was a specific URL you could try running a HEAD command on it to get the response code I suppose ...

If the Microsoft XML parser is installed (or can be) on your webserver, then you can create a HTTP REQUEST for a page on the remote server. If you do your error handling, you can then return a message if the request fails.

It's the XML Parser that I'm using to grab the data from the other site so I guess I'll just read up on error handling. Thanks.

found this on ASP FAQ :

<% 
    ' deliberate typo: 
    url = "http://www.espn.co/main.html"  
    set xmlhttp = CreateObject("MSXML2.ServerXMLHTTP")  
    on error resume next 
    xmlhttp.open "GET", url, false 
    xmlhttp.send ""  
    if err.number <> 0 then 
        response.write "Url not found" 
    else 
        Response.write xmlhttp.responseText  
    end if 
    set xmlhttp = nothing 
%>

This should do what you are looking for?
