asp.net http handler

Attribute	Description
Path	The path attribute can contain either a single URL path or a simple wildcard string (for example, *.aspx).
Type	Specifies a comma-separated class/assembly combination. ASP.NET searches for the assembly DLL first in the application's private \bin directory and then in the system assembly cache.
Verb	The verb list can be either a comma-separated list of HTTP methods (for example, "GET, PUT, POST") or a start-script mapping (for example, the wildcard character * [an asterisk]).
