Hello!
I have a page that cfoutputs text from a database and allows a user to
update the text content. The user simply fills in a form field and clicks
update. I use an update template that updates the database with the new text
the user typed in.
At the end of the update template I use <CFLOCATION> to go back to the page
in question. Unfortunately, the browser keeps showing a local copy and not
the updated version, unless I hit refresh on the browser.
I searched the CF resources for an answer and thought I found it at
houseoffusion (excerpt at bottom )
with:
<CFLOCATION URL="index.cfm?norefresh=#Rand()#">
Unfortunately, the browser still loads a local copy even though the URL is
always different.
Any help would be greatly appreciated!

-----from Aiden Whithall's FAQ -----------
"The key to creating a workaround for this situation is to know that
browsers identify a page by its URL--if the URL is the same as the one it
just cached locally, it uses the local copy. Accordingly, you can simply
append a dynamically created variable name to the URL, thereby producing a
new URL and forcing the browser to make a subsequent call to the server to
retrieve the new, and up-to-date, page. Here is an example of the code you
can use to do this:
<CFLOCATION URL="index.cfm?norefresh=#Rand()#">
Rand() returns a random number in the range of 0 to 1, including fractions,
so the URL will be different each time you call it, which forces the browser
to request the page again from the server. That, in turn, ensures the most
current information will be displayed."
