[Catalyst] [OT] ASP.NET MVC

[Octavian Rasnita]

Hi,

I haven't read anywhere that : Local is deprecated, and I use it very often. 
Why is it deprecated? I found it works very well, and it is the most simple 
solution.

I was also curious about chaining, but I couldn't find a tutorial that 
explains in which cases I could need to use chaining, and how to use it.

I think that it could be helpful to have a POD document that lists all the 
types of mapping an URL to a method, and explain:
- for which cases can the current type be used;
- if the current type is the recommended, or best considered way for a 
certain case;
- which could be the disadvantages of the current explained type;
- explain how to use the current type, and how to get the PATH_INFO 
parameters.

By the word "case" I understand the different types of URLS that could be 
used, for example:

/bla/blu/bli
/bla=1/blu=2/bli=3
/bla/1/blu/2/bli/3
...
