// This is supposedly a fix to define the web sql database size so that web sql db will work, but it doesn't seem to be working
- (void)webView:(WebView *)sender frame:(WebFrame *)frame exceededDatabaseQuotaForSecurityOrigin:(id)origin database:(NSString *)databaseIdentifier
{
    static const unsigned long long defaultQuota = 5 * 1024 * 1024; //5 MB
    if ([origin respondsToSelector: @selector(setQuota:)])
    {
        [origin setQuota: defaultQuota];
    }
    else
    {
        NSLog(@"could not increase quota for %@", defaultQuota);
    }
}

And I have this in my preferences definitions list:

// Enable web sql db -- This does not appear to work...
// A possible fix would be to discover how to define the actual webdb quota size.
[prefs setDatabasesEnabled:YES];
