• How to get final destination URL from AJAX?

  - by Maurice Lam

  When I do an XMLHttpRequest, I always get redirected automatically to the URL (presumably by the headers of the response). For example, if I query "http://www.stackoverflow.com" I will be redirected to "http://stackoverflow.com". How can I get that final URL? (http://stackoverflow.com/ in the example) I checked in the response headers but I cannot seem to find it. (I just used the GET/POST method not HEAD).

• Amazon S3 permissions

  - by Joe

  Trying to understand S3...How do you limit access to a file you upload to S3? For example, from a web application, each user has files they can upload, but how do you limit access so only that user has access to that file? It seems like the query string authentication requires an expiration date and that won't work for me, is there another way to do this?

• Main Memory Database with C++ Interface

  - by myahya

  I am looking for a main memory database with a C++ interface. I am looking for a database with a programmatic query interface and preferably one that works with native C++ types. SQLLite, for example, takes queries as string and needs to perform parsing ... which is time consuming. The operations I am looking for are: Creation of tables of arbitrary dimensions (number of attributes) capable of storing integer types. Support for insertion, deletion, selection, projection and (not a priority) joins.

• PreparedStatement.setString() method without quotes

  - by Slavko

  I'm trying to use a PreparedStatement with code similar to this: SELECT * FROM ? WHERE name = ? Obviously, what happens when I use setString() to set the table and name field is this: SELECT * FROM 'my_table' WHERE name = 'whatever' and the query doesn't work. Is there a way to set the String without quotes so the line looks like this: SELECT * FROM my_table WHERE name = 'whatever' or should I just give it up and use the regular Statement instead (the arguments come from another part of the system, neither of those is entered by a user)?
