CFHTTP and web caching... will this work?

Instead using an FTP transfer to get an XML file off a remote web server I thought about using CFHTTP to get it.  I was then told, it may not be good because the my internet connection is running through caching servers.

Then I started to think, what if I added a random number in a URL parameter in my CFHTTP :

<cfhttp url="http://www.website.com/file.xml?noCache=#RandRange(1,999)##RandRange(1,999)##RandRange(1,999)#" method="get"...>

Will this defeat any caching issues?

I don't want to say I am 100% sure that would work but it should. Its the same idea as we do to get around caching servers;  we append a page request id to all the URL's. From what I can tell it has worked.

additionally unless you are doing it more often than 1 second why not just use now() instead of random numbers.

<cfhttp url="http://www.website.com/file.xml?noCache=#urlencodedformat(now())#" method="get"...>

P_CF_DEV is right, but, instead of using now() or a random number, I would suggest using getTickCount()... it's unique for every millisecond...

<cfhttp url="http://www.website.com/file.xml?noCache=#getTickCount()#" method="get"...>

HTH,
