Question

I used ASIHTTP request to access web html page.

ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:[NSURL URLWithString:requestURL]];
[request setTag:selectTag];
[request setDownloadCache:[ASIDownloadCache sharedCache]];
[request setCachePolicy:ASIAskServerIfModifiedCachePolicy | ASIFallbackToCacheIfLoadFailsCachePolicy]; 
[request setCachePolicy:ASIOnlyLoadIfNotCachedCachePolicy];
[request setDelegate:self];


[request startAsynchronous];

If I navigate from an ViewController to another.

Is it possible to cancel this async http request if it has not yet triggered ‘requestFinished’?

Welcome any comment

Following method is present with ASIHttpRequest, you can use it to cancel the request –

- (void)cancel {
        [self performSelector:@selector(cancelOnRequestThread) onThread:[[self class] threadForRequest:self] withObject:nil waitUntilDone:NO];    
}

You can call this method-

[request cancel];
