Description

Currently the XmlStore? has preventCache: true by default. This should be modified to be an attribute that can be passed when the store is created. I encountered this problem when trying to integrate Dojo with CodeIgniter? which uses urls like: /controller/function/argument rather than controller.php?function=X&argument=X. The problem I had was that my store was calling "/main/xml/" which is a function in main.php called xml() which outputs an xml string. When the store is created and it calls the url for the xml it calls "/main/xml/?dojo.preventCache=XXX" which results in a 404. As my app handles any cacheing through headers (and caching is not a major concern for me) the "dojo.preventCache=XXX" is not needed and I'd like to be able to turn it off. Currently I have to edit dojox/data/XmlStore.js to do so.

I haven't checked all the other store types, but I assume this is the case with most, if not all of them.

I agree that this needs to be fixed. I'm implementing a page using XmlStore?, and the XML file is being redownloaded with every fetch (pagination, filtering, etc). Is there a reason why this data store would want to prevent caching?

The reason is the store is designed to operate both as remote AND local. It has a serverQuery mode, where you would want to prevent caching since the server is doing all the query processing.
