Hi everyone,
I am trying to control the caching behavior of a WebView, but I am
having some trouble... Here's the scenario... Imagine you are going on
a plane trip and you want to have with you the freshest content of your
favorite web sites. Now imagine that you have an application that goes
to your favorite web sites, downloads all the content and pushes
everything into the cache of a WebView, so that you don't have to do
that work yourself - by going to a bunch of sites and saving the pages
to your desktop. I want to write an application with this same level of
control over the cache - essentially mapping NSURLRequests (the
requests to web sites) to NSCachedURLResponse (the content of the web
sites) items in the sharedURLCache.
The problem is that it looks like this is not so simple, if this small
thread is any indication:
http://cocoa.mamasam.com/COCOADEV/2003/07/1/68281.php
In the thread, Scott Anguish mentions that an option is to subclass
NSURLProtocol.....
Does anyone have any experience with this? The code listed in the
thread above seems to be doing all the right work, too bad it's not so
simple to manipulate the NSURLCache and make it work together with a
WebView. Any help would be greatly appreciated.
Thanks!
Edison Thomaz
