Question

i wonder how twitter did their URL like this

https://twitter.com/#!/twitter

is it a unique method via ruby or it’s something i can do with .htaccess and php because as far as i know this # sign is used to send user to a certain block on the page

also is it possible to use
other tags for example & or % or $ etc.

thanks in advance

Answer 1

This is what you should read to find out what #! means:

1. A proposal for making AJAX crawlable
2. Getting started with #!
3. Full Specification
4. Why it might be not a good idea

However, if you’re just doing this for aesthetics because you like #! more than ? or &: don’t do it. It’s not worth the hassle.
