How can I check if a https:// URL exists with cfhttp?

Hello,

I have some code that can be used to check if a URL exists where arguments.u is a full URL (http://www.google.com/ for example) - from this I can determine if a URL exists or not as part of a broken link checker for our content.

<cfhttp method="head" url="#arguments.u#" resolveurl="no" throwonerror="no" />

But, in some cases, that arguments.u will be a https URL, like https://www.keeleklikk.ee/ - which is a valid URL and I can access it no problem.

But this gives me the following response from the cfhttp:

How can I modify my cfhttp call so that it properly checks https URLs as well as regular http ones?

Thanks,

Phil.
