URL Validation

[jenn1]

Hi,
Is there a way to check if a URL is exists? For instance to check to see if www.adobe.com exists. Can this be done with cfhttp?

Thanks!

You can use CFHTTP, and then check to see if there is any amount of size to the returned file. That does NOT guarantee that there is any useful content or anything like that, of course.

Keep in mind that even a bad URL will return SOME content such as "File Not Found" or something like that. For that reason, you dont want to base your decisions on whether or not the returned file size is greater than zero.

You can also use the status property of the cfhttp results to see if you
get an OK 200 status or some other status returned by the remote server.

Remember that a new url might not be picked up by spiders yet.

spiders have absolutely nothing to do with this whatsoever.
