NSURLProtocol subclass changes URLs automatically
I am using UIWebView and have implemented own subclass for NSURLProtocol to intercept PDF File from the response. Everything was working fine. but, I realized for some of our website where Re-writing proxy is implemented. URL is getting change & that causes HTTP 404.
To understand the cases I tried to return NO in canInitWithRequest. At that time it worked perfectly but as I send YES there its subsequent requests URL gets changed.
This is what I have written in startLoading Method
- (void)startLoading {
NSMutableURLRequest* request = self.request.mutableCopy;
NSLog(@"%@",request.URL);
NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration];
NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
if([response isKindOfClass:[NSHTTPURLResponse class]]){
NSDictionary *aInfo = [(NSHTTPURLResponse*)response allHeaderFields];
if([(NSString*)aInfo[@"Content-Type"] containsString:@"application/pdf"]){
// Code to save DATA as PDF File
//in Document Directory via call back to other classes.
[self.client URLProtocol:self didReceiveResponse:response cacheStoragePolicy:NSURLCacheStorageAllowedInMemoryOnly];
[self.client URLProtocol:self didLoadData:nil];
[self.client URLProtocolDidFinishLoading:self];
}else{
[self.client URLProtocol:self didReceiveResponse:response cacheStoragePolicy:NSURLCacheStorageNotAllowed];
[self.client URLProtocol:self didLoadData:data];
[self.client URLProtocolDidFinishLoading:self];
}
aInfo = nil;
}
}];
[postDataTask resume];
}
