Could you please explain how this compression works.
I keep seeing this as it is being compressed and
decompressed at the server, or is it being compressed
at the server and decompressed at the client.

It's been running like a champ for us over the last three days on a
moderately high volume site. I can't imagine that the CFX overhead
would be that much higher than ISAPI overhead. CFX_GZip is a good
multi-threaded tag...
The overhead is most likely on the cache file writes and cache

Ok I understand what has been done the
only thing I see as a problem is that
the tag is writing a file. Now without
locking or without a unique name
something bad is bound to happen. And
once you put locking on the writing of
files there is gonna be a slowdown.

The overhead is most likely on the cache file writes
and cache reads. You just gave me an idea for a work
around that could be better and faster than all the
options we have just discussed. With both ISAPI and
CFX, the system has to compress each and every single
page output as it is a

Okay... I think the tag is done. I made a few more changes (see
below).
I also figured out how to automagically compress all the pages in
your site w/ one little change.
Here's what I did find:
In the Application.cfm, I put this code:

Why use a cfx tag with coldfusion to compress html output when you can use
IIS 5.0's builtin gzip/deflate compressors? I bet the cfx/cf overhead is
much higher and not

You could write a CFX_J tag that would use the GZip compression and send it.
If you're using a Fusebox-style implementation, then you'd encapsulate
you're entire page in a custom tag (i.e.
CF_HTMLCompress/CF_HTMLCompress.) The custom CF tag would be something
like:

That's true, but it doesn't mean you can't do it in CF...
Below is a custom tag that will do just that, provided you have
CFX_GZip installed (freely downloadable from the tag gallery).
I'm not sure
Cool... I'll check it out!
Thanks for the help.
