I wrote a mini-article about this at http://doug.nottage.com/cf Actually
while it sounds good, it still taxes your CF resources on that server. The
faster way is to dynamically write the IMG SRC= information in the .cfm page
and have these images pulled from a non-CF server. This can be a pure IIS
server, a proxy or a highly optimized solution like Akamai or Digital
Island. Pulling the info via a database, even when in RAM, takes up your
very valuable CF threads which could instead be used to create your CFML
even faster for other pages. The point here being CF really doesn't gain
you anything because an IIS-only server will also store items in RAM if
there is a sufficient amount of it and a proxy does this even faster. Not
to mention, these are usually far cheaper solutions which don't even touch
your database or CF servers. Would it work? Yes, it would but you'd have
to put a CFCONTENT in front of the binary data or append this info when the
image is stored in data. I just feel the method I'm proposing would be
cheaper, faster and not put your DBMS or CF systems under any additional
load.
Let me know what you try .

Subject: CF image server?
Hi All,
Here's an idea that popped into my head as I awoke from a nap....
Someone else's idea of serving images from the SQL7 server was shot down in
the group for a couple good reasons: single point of failure and load.
However let's take that idea step further and combine it with the consensus
that making CF sites that live in RAM (cache queries and/or structures).
Let's say have have several high end servers each having 1 gig of RAM. Half
of these servers are for CF pages. The other half are serving up images off
their 10K rpm raid 0 drives the old fashion way.
Now let's pretend the CF servers return a img src with
http://images.myserver.com/index.cfm?fa=imageServer&file=imageName or
something like this or not. My image servers now are running CF which have
cached a query of all the images stored in my database that 1 GiG would
hold.
What I'm I missing? Has anyone tried this? Would this deliver our users
their images faster than before?
TIA,
Rick
