2 applications on one server
hi we are trying to place 2 applications on one vps for the first time and would like some guidance on whether there is anything we need to think about in terms of conflicts etc... basically i am confused as to how this works with 2 application.cfc's each one of the applications should be totally seperate but how does coldfusion know which application.cfc to use and how come they dont conflict with each other? thanks ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:321656 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
Re: 2 applications on one server
each one of the applications should be totally seperate but how does coldfusion know which application.cfc to use and how come they dont conflict with each other? When you run a CF file, CF looks within the directory of that file for Application.cfc or Application.cfm. If it doesn't find either, it looks in the parent directory, and so on until it finds one of those files or it reaches the root of the drive. So, if you want separate applications, you put them in separate directories.

As the documentation discuss in great length with examples and pictures... ColdFusion starts with the location of the file being request and looks in that directory for first an Application.cfc file and then an Application.cfm. If it does not fine either of these in that directory it goes up to the parent directory and looks for first an Application.cfc and then an Application.cfm file. It contiues this search up the directory tree until it finds either an Application.cfc file or an Application.cfm file or reaches the *file* root directory. Note this can be above the web root. If your two applications are in separate and distinct directory structures and these directory trees have separate Application files then the applications will be independent. ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:321662 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
Re: 2 applications on one server
we have 2 different directories for both applications however will the application scope conflict? we use modelglue and coldspring which loads items into the application scope, but we are noticing these are conflicting... it seems as though when we go to one application it is overwriting the application variables of the other application Richard White wrote: basically i am confused as to how this works with 2 application. cfc's each one of the applications should be totally seperate but how does coldfusion know which application.cfc to use and how come they dont conflict with each other?

Re: 2 applications on one server
not if you name each application with a unique name. We run thousands of applications on a single server, each with a unique name, and there are no problems.

Re: 2 applications on one server
Richard White wrote: we have 2 different directories for both applications however will the application scope conflict? Ahh different issue. ColdFusion distinguishes different applications by the application name string. Any template, in any directory running under any application cfc or application.cfm file and the same server that share the same application name will be considered to be the same application. And thus they will share the same application scope variables. So change the name of one of the applications within either the this.name = or cfapplication name= command that you used. ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:321670 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4

Re: 2 applications on one server
thanks for your comments it is now seperating the 2 but the names were different the only thing we changed was: cfcomponent cfset application.name = Project1/ to cfcomponent cfset this.name = Project1/ why would changing it from 'application' to 'this' rectify this conflict thanks Richard White wrote: we have 2 different directories for both applications however will the application scope conflict?

That variable is not the application name, it's just a variable called name. Without this.name, your application doesn't have a name.

Re: 2 applications on one server
Richard White wrote: why would changing it from 'application' to 'this' rectify this conflict thanks Because it does! :-) I don't know why this is but this.name and the equivalent cfapplication name= don't set a variable names application.name they set a variable named application.applicationName. And I honest don't know what would happen if you tried to set application.applicationName directory. I suspect it would be unpredictable.

Re: 2 applications on one server
thanks for all your comments, i also read that in the documentation but it didn't even register that this.name and application.name wouldn't be equivalent... but it does make sense thanks again for the help thanks for your comments it is now seperating the 2 but the names were different the only thing we changed was: cfcomponent cfset application.name = Project1/ to cfcomponent cfset this.name = Project1/ why would changing it from 'application' to 'this' rectify this conflict Within Application.cfc, this.name is how you name an application, and application.name is how you refer to a variable called name from within the Application scope.
