What is the verb="*"?

Can any one tell me , when we register the custom HTTPHander in web.config like below

 <add verb="*" path="SampleHandler.new" 
    type="SampleHandler, SampleHandlerAssembly" 开发者_C百科/>

in this What is the meaning of the verb="*" and what is the it's use?

It means all HTTP verbs: GET, POST, HEAD, PUT and DELETE

The verb list can be either a comma-separated list of HTTP verbs (for example, "GET, PUT, POST") or a start-script mapping (for example, the wildcard character * [an asterisk]).

It means that the handler will execute for all verbs - ie. GET, PUT, etc.

It can be used to specify that, for example, a certain handler should only process POSTs not GETs.
