Hopefully there's a simple solution to this. I'm setting up a redirect for old search listings, but I don't want any of the query string to carry over. The current rule is: redirect 301 /blog http://newdomain.com But this would redirect the following: http://www.olddomain.com/blog/2009/11/article-name-etc To this: http://newdomain.com/2009/11/article-name-etc When I just want: http://newdomain.com Can this be done in the simple 301 redirect, or will I have to write a mod_rewrite rule?Read the article

Is it safe to use connection.createStatement().executeQuery(String query);?

If multiple queries are executed in one method by one connection it would use much less code if instantiating and closing each statement wasn't strictly necessary.Read the article

- by mystify
Example: I want to do this: METHODNAME(5) { // do something } which results in: - (void)animationStep5 { // do something } Is there any way to do this?
