objective c - How access to response http headers from 'didReceiveAuthenticationChallenge' delegate method -

-

I need to deal with an HTTP authentication (401) using the NSURLConnection class, so I used "Connection: didReiveiveAuthenticationChallenge" Has implemented. Representative method

In this method, to answer the server challenge, I need the information contained in the HTTP server response header (WWW-Authentication Header). My problem is how can I use this header with this method?

(I noticed that the feedback headers are available from the NSURLResponse object (allHeaderFields method), but this object has been passed to the "Connection: didReiveiveResponse:" delegate method, too late to answer the server challenge Done.)

Regards Sebastien.

NSUrutitization challenge has a -failureResponse way. If that object is a NSHTTPURLResponse (and it should be for an HTTP connection!), Then you can query it for -allHeaderFields .

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
