Mutable NSHTTPURLResponse or NSURLResponse

Question

I need to modify response headers in an NSURLResponse. Is this possible?

Answer 1

You can read them into a NSDictionary using the allHeaderFields method.

    NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;
    NSDictionary *httpResponseHeaderFields = [httpResponse
allHeaderFields];

To be 100% safe you'd want to wrap it with

if ([response respondsToSelector:@selector(allHeaderFields)]) {... }
