A method and system for separating hypertext transfer protocol session. The method includes: detecting at the client a condition that a server is to be requested to instantiate same application during same hypertext transfer protocol session; obtaining from the server another hypertext transfer protocol session identifier corresponding to a service instance to be instantiated and setting the hypertext transfer protocol session identifier in the current session as a hypertext transfer protocol session identifier corresponding to a service instance that is to communicate with the server. The system includes: a session manager configured to detect a condition that a server will be requested to instantiate an application during a current HTTP session and a session agent configured to: (i) obtain from the server a second HTTP session identifier and (ii) set the second HTTP session identifier in the current session as a HTTP session identifier.
