Can you show the code for doing a URL rewrite using JAVA code on Google App. Engine?
I am trying to create a proxy for DropBox using Google App. Engine and want to rewrite the URLs.

Does anyone know how to do this with java and GAE?

Thanks for the post. I need this on my new app.

The www part is still useful for the speed freaks out there, check here: http://developer.yahoo.com/performance/rules.html#cookie_free

had to add another comment as i forgot to check the “notify me” tickbox!

does anyone know how to do this in java app engine?

Very simple and useful hack, thanks for post =)

Wait… Where did my comment go? I swear I posted a comment just a second ago. WTF? Oh well, I guess I didn’t press Post or something. Anyway…

@Chris Wellons: Yeah, I force it here, but I think I did it because of some legitimate reason at the time. I think it had something to do with page rank for www URL being higher than for the non http://www... Still, it shouldn’t matter if I just 301 redirect everything.

Just for shits and giggles I tried forcing the non-www version of the URL and WordPress went into some sort of self-redirecting loop. So I’m guessing something is broken somewhere and I need to locate and fix it before I do the switch.

Yes, I agree it is unnecessary and usually when I link back to my blog I write the URL without WWW.

@Matt`: No worries. If the blog goes offline it’s usually Dreamhost fucking up, not me. I’m usually very cautious about not screwing around with settings that are working well for no reason. Well, except today when I did mess with them and knocked the site down for about 3 minutes. :P

Some day I am going to want to do things, and the archives of this website will be crazy-useful.

So don’t you do anything crazy like going offline, I might need all those code examples for doing useful thing X in language Y :P

Useful hack. I hate needlessly ugly URLs. When possible, a dynamic site should look like a simple file hierarchy without any GET parameters.

Imagine if the URL to this post was the following!

http://www.terminally-incoherent.com/wordpress/blog.php?year=2009&mont h=5&day=11&postid=29423933740

Also, can we all finally drop the www part of URLs someday? Everyone insists on using it, but it’s unnecessary. (I do see that you force it here! :-P)

My favorite examples of needlessly ugly URLs are just about any Slashdot URL, and the wiki URLs from the mismanaged TV Tropes website. This is the canonical TV Tropes main page URL (you get redirected here if you try just the domain),

http://tvtropes.org/pmwiki/pmwiki.php/Main/HomePage

It contains “pmwiki” not once, but twice, and probably shouldn’t have it visible at all. The entire “pmwiki/pmwiki.php/Main/” is a big static chunk of ugly. Hey, no www though! And it looks like a file hierarchy. So, there are some good things here. I think any of these would be much better.

(I had more stuff written, but there is some kind of URL limit, then your spam filter kicks on. Or it doesn’t allow lists of URLs. We are losing the spam war to crappy spam filters.)

Ok, I’m done ranting!
