[geoffrey.mcgill]

Can u test it in chrome frame?

I apologise. It was a long day yesterday.

No Prob Geoff... The issue can be marked solved as soon as you add a property somewhere for disablePostCache. Or rather update the code to not cache both post and get.

Trying to override Ext.data.Connection.request.

Its been really long we are trying to find a solution for this and finally it looks near :)

Hi,

Please update from SVN. Now POST ajax requests (DirectEvent/DirectMethod) with cache buster by default under Chrome Frame
Also we added DisableCaching and DisableCachingParam properties for overriding for particular direct event/method. On the global level you can do it via javascript

Ext.net.DirectEvent.disableCaching 
Ext.net.DirectEvent.disableCachingParam

Hi Vlad,
I would like to get to your notice that, its important this setting remains same for all browsers.

Reason being, in my tests, on pageload, GET request is cached, however, on subsequent post request, the cache is invalidated and then if you again request the page, its not loaded from cache but from the server.

In tht case, caching will work only in Chrome Frame and not in other browsers. I request you to make this default in other browsers.

I am still using an older version of Ext.Net, and at this stage cannot update from SVN. I am looking at overriding the Ext.net.DirectEvent.request method, but having some issue.

Can you plz check the attached file and tell me if its correct?

I have tested, and its working perfectly. Just wanted ensure I have not missed anything.

Thanks,

Hi,

Ok, now POST ajax requests with cache buster by default for all browsers.

You can use following code to accomplish that

Ext.net.DirectEvent.on("beforerequest", function(conn, o){
        var method = o.method || this.method || ((o.params || o.xmlData || o.jsonData || o.form) ? "POST" : "GET"),
            url = o.url || this.url,
            form = Ext.getDom(o.form);
            
        if(form){
            url = url || form.action;            
        }
        
        if(method === "POST" && (this.disableCaching && o.disableCaching !== false)){
            if (Ext.isFunction(url)) {
                url = url.call(o.scope || "window", o);
            }
            var dcp = o.disableCachingParam || this.disableCachingParam;
            o.url = Ext.urlAppend(url, dcp + '=' + (new Date().getTime()));
        }
}, Ext.net.DirectEvent);

You can ignore my last post....
All's well here!

Thank you so much!

Which turns off caching on all non-GET operations, so POST will not be fed from the cache ever.

Hi michaeld,
Thanks for your reply, but this issue was sorted long back. Almost 2.5 yrs back :)
