ASIHTTPRequest Cache response data

Question

I'm trying a lot with ASIHTTPRequest to cache the response data, I have read the documentation and tried many solutions, but no luck :(

This is my code:

_request = [[ASIFormDataRequest alloc]initWithURL:[NSURL URLWithString:NSLocalizedString(@"kBaseUrl", nil)]];
_request.delegate = self;
[_request setDownloadCache:[ASIDownloadCache sharedCache]];
[[ASIDownloadCache sharedCache] setShouldRespectCacheControlHeaders:NO];
[_request setCachePolicy:ASIAskServerIfModifiedCachePolicy|ASIFallbackToCacheIfLoadFailsCachePolicy];//ASIAskServerIfModifiedCachePolicy|ASIFallbackToCacheIfLoadFailsCachePolicy
[_request setSecondsToCache:60*60*24*2]; // Cache for 2 days
[_request setCacheStoragePolicy:ASICachePermanentlyCacheStoragePolicy];
[_request setDefaultResponseEncoding:NSUTF8StringEncoding];
[_request setDidFinishSelector:@selector(doneLoadingBody:)];
[_request setDidFailSelector:@selector(failedLoadingBody:)];
[_request setRequestMethod:@"POST"];
[_request setShouldContinueWhenAppEntersBackground:YES];
[_request setPostValue:@"someValue" forKey:@"name"];
[_request setPostValue:@"someValue" forKey:@"key"];
[_request setPostValue:@"someValue" forKey:@"key"];
[_request startAsynchronous];

if ([_request didUseCachedResponse] == NO) {

    NSLog(@"Did not Cache Body");

}

You're using ASIFormDataRequest and it's basically a POST operation.

Since POST is not an idempotent operation, i doubt it is cacheable.

Maybe you should start testing your cache mechanism with a GET request.

Some reference: Is it possible to cache POST methods in HTTP?
