dears after looking thoroughly in my be convince hosting options I found google app engine because it is dynamic on scaling automatically based on demand and that is good because it will save me from crashing down on spikes and also will save me on bills,,, so I started installation and google support are great and we stopped here :
google support said: This is if the initial setting of the permission of the directory worked but
I'm not familiar how the temporary/session directory is being used by the application. Will it be used once during the SocialEngine installation or going forward. Because if it will be used going forward, you will have to write a piece of code to programmatically change the permission of directory `temporary/session`. This will ensure that every time a new instance is created (on scaling or deployment) the app will have the access to that directory.
please dose any1 have any good suggestion on this matter?
thanks in advance
