HTTP Vesion Implemented by Servlet 2.3

[vijay saraf]

Hello All,

I want to know the version of http implemented by servlet 2.3( i am thinking so because servlet implemets HttpServlet).even i am not sure that http version depends on servlet version or not.if it depends on servlet container please tell me which version is used by tomcat4 .

As stated in the spec :

The minimum required version of the HTTP specification that a container must implement is HTTP/1.0.
It is strongly suggested that containers implement the HTTP/1.1 specification as well.

There will be restrictions for containers supporting only HTTP/1.0.
For example :

In containers that support only HTTP/1.0, only the doGet, doHead and doPost methods are supported, as HTTP/1.0 does not define the PUT, DELETE, OPTIONS, and TRACE methods.

Tomcat4 does support HTTP/1.1.
