Server Scope / UDFs
Is there a way to force CFMX to load some vars into server scope when the service is started? Also, has anyone had any negative reaction to loading a CFC into server scope? I basically have a library of UDFs I want globally available that I thought I would throw into a CFC and load into server scope. This way the UDF's would be available to all code, including typically blackboxed code like other CFCs and Custom tags, etc. Lastly, if someone has figured out a way to load UDFs in such a way that they behave like native functions, I would love to hear about it. (ie, globally available on the MX box without having to scope them). I would prefer to do #formatphone()# rather than #server.udfs.formatphone()#.

However in MX you wouldn't need to worry about it. === Raymond Camden, ColdFusion Jedi Master for Hire Email: [EMAIL PROTECTED] WWW : www.camdenfamily.com/morpheus Yahoo IM : morpheus "My ally is the Force, and a powerful ally it is." - Yoda ~| Archives: http://www.houseoffusion.com/cf_lists/index.cfm?forumid=4 Subscription: http://www.houseoffusion.com/cf_lists/index.cfm?method=subscribe&forumid=4 FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Signup for the Fusion Authority news alert and keep up with the latest news in ColdFusion and related topics. http://www.fusionauthority.com/signup.cfm

Note that you cannot output HTML from methods of CFCs that are stored in shared scopes (but, hey, you wouldn't be outputting HTML from CFCs anyway, would you?). > Lastly, if someone has figured out a way to load UDFs in such a way > that they behave like native functions, I would love to hear about it. Nope, you need to scope them. Sure, you could create a 'local' alias via Application.cfm () but that won't be available inside custom tags for example.

I hope the "events" thing happens someday. As easy as it would be to add to every application.cfm on the server it would be far cooler to not have to. :) > Well, it is not recommends for CF5 because you would need to lock every > use of it. However in MX you wouldn't need to worry about it. Yeah, this is MX, so not as much of an issue.

I was more looking for a "hack" ala putting custom tags into the \wwwroot\WEB-INF\cftags directory so they be called like native tags. Oh well. Only a little additional typing. ~| Archives: http://www.houseoffusion.com/cf_lists/index.cfm?forumid=4 Subscription: http://www.houseoffusion.com/cf_lists/index.cfm?method=subscribe&forumid=4 FAQ: http://www.thenetprofits.co.uk/coldfusion/faq This list and all House of Fusion resources hosted by CFHosting.com.

Well, personally, I'm not much of a fan of the idea of loading UDFs into
memory anyway - memory is good for storing data, but is wasted on code.
However, if you really want to do this, there's no reason why you can't
write a batch file to start CF, then request a CF file using an HTTP
command-line client, like wget, to initialize your data.

Well, functions are just data. The benefit is that you don't have to include the file that defines the function...

The benefit is that you > don't have to > include the file that defines the function... I have a sneaky suspicion that is faster than ... or the cfscript equivalent... I've never load tested it, but i would expect that the CF processing engine, whether it's CF 5 pcode or CF MX Java has to take more time to read in and create the function than to assign a pointer to it. The pointer is after all only a byte or two of volatile memory lookup vs. the function definition which is invariably larger, plus time to actually parse and validate the code and make sure it's not missing a double-quote or a close-parenthesis somewhere, etc. Does anybody know for sure? Has anyone done any load testing to compare them? s. isaac dealey954-776-0046 new epoch http://www.turnkey.to lead architect, tapestry cms http://products.turnkey.to certified advanced coldfusion 5 developer http://www.macromedia.com/v1/handlers/index.cfm?ID=21816 ~| Archives: http://www.houseoffusion.com/cf_lists/index.cfm?forumid=4 Subscription: http://www.houseoffusion.com/cf_lists/index.cfm?method=subscribe&forumid=4 FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Get the mailserver that powers this list at http://www.coolfusion.com
