ColdBox 3.6 - Disable Session Management?

Communities ColdBox HMVC
#1

HI folks,

This thread builds upon the discussion here - https://mail.google.com/mail/u/1/?ui=2&shva=1#search/from%3Ame/13ff25befd2b3a23 - in terms of load on the app/system.

My app essentially doesn’t need to use session or client managment, so I disabled the settings in my Application.cfc. Ultimately I’m trying to remove as much strain on the server as possible, thus removing the need for new sessions to be spun up.

I also removed any DI references to the sessionStorage plugin, and changed my CB config to use ‘application’ for the flashURLPersistScope setting.

When i disabled the settings I received the following error (see below).

It seems that (by default ??) CB requires session management to be on? Is there a way to disable this, or could I be missing something?

Thanks!

Nolan

Session scope is the default storage location for Flash RAM. You should be able to switch Flash RAM to store elsewhere in your ColdBox config:

Thanks Brad, it seems like there is no way to disable flashRam though. I don’t need to use this at all. Could I achieve this by setting it to use the default cache which uses the application scope?

Thanks

#4

Yes, just set it to something other than session and it won’t try to access the scope.

Thanks!

Hi Brad,

I tried changing the setting to cache and cluster and I still get the error. It’s happening really early in the ColdBox request lifecyle. Below is the full stacktrace. Could there be something else I’m missing? Thanks.

Show us your config, please.

Create a dummy flash.

your config:

flash = {
scope = “com.common.model.flash.DummyFlash”
};

your DummyFlash:

component extends=“coldbox_3_5_3.system.web.flash.AbstractFlashScope” hint=“A customized implementation of the ColdBox flash scope.”{
public any function init(controller) {
super.init(argumentCollection=arguments);
return this;
}

public any function getFlashKey(){
return ‘’;
}

public any function saveFlash(){
return ;
}

public any function flashExists(){
return false;
}

public any function getFlash(){
return {};
}

public any function removeFlash(){
return ;
}
}

Hi guys,

Aaron, thanks for the snippet. I may try that approach.

Brad, here is my configure function in ColdBox config:

function configure(){

//converts the coldbox app mapping to a dot class path for instantiations, not part of a regular config

var appMappingDotNotation = reReplace(appMapping,"(/|\)",".",“all”);

// coldbox directives

coldbox = {

//Application Setup

appName = “My App”,

eventName = “event”,

//Development Settings

debugMode = false,

debugPassword = “”,

reinitPassword = “”,

handlersIndexAutoReload = false,

configAutoReload = false,

//Implicit Events

defaultEvent = “General.index”,

requestStartHandler = “Main.onRequestStart”,

requestEndHandler = “Main.onRequestEnd”,

applicationStartHandler = “Main.onAppInit”,

applicationEndHandler = “”,

sessionStartHandler = “”,

sessionEndHandler = “”,

missingTemplateHandler = “”,

//Extension Points

UDFLibraryFile = “includes/helpers/ApplicationHelper.cfm”,

coldboxExtensionsLocation = “”,

modulesExternalLocation = [],

pluginsExternalLocation = “”,

viewsExternalLocation = “”,

layoutsExternalLocation = “”,

handlersExternalLocation = “”,

// Register your RequestContextDecorator within your Coldbox.cfc or your ColdBox XML file by telling ColdBox where the CFC lives

requestContextDecorator = “model.coldbox.RequestContextDecorator”,

//Error/Exception Handling

exceptionHandler = “Main.onException”,

onInvalidEvent = “General.invalid”,

customErrorTemplate = “”,

//Application Aspects

handlerCaching = true,

eventCaching = true,

proxyReturnCollection = false,

flashURLPersistScope = “cache”

};

#9

I think I got it fixed.

My coldBox config only had the flashURLPersistScope = “cache” setting.

I added in:

// flash scope configuration

flash = {

scope = “cache”,

properties = {}, // constructor properties for the flash scope implementation

inflateToRC = true, // automatically inflate flash data into the RC scope

inflateToPRC = false, // automatically inflate flash data into the PRC scope

autoPurge = true, // automatically purge flash data for you

autoSave = true // automatically save flash scopes at end of a request and on relocations.

};

and the error went away. are both required? Is the first setting necessary?

Thanks.

#10

You’re using a setting which is no longer valid in the config:

flashURLPersistScope= “cache”

http://wiki.coldbox.org/wiki/Compatibility:3.5.0.cfm#flashURLPersistScope_Removed

Use the flash struct like Aaron showed.

flash = {
scope = “blah”
};

Thanks!

Check out my last reply. The setting you had first been using is no longer part of ColdBox.

Thanks!
