ABSTRACT:
A general, event/handler kernel extension system is implemented. Network server extension architecture isolates and exploits the ability to derive responses on the same interrupt the original request was received on using non-paged memory. TCP network server extensions are implemented. A technique is defined for facilitating immediate completion of connection requests using pre-allocated connection endpoints and describes an approach to recycling these connection endpoints. A hybrid HTTP extension implemented partially in user space and partially in kernel space is defined that provides explicit or transparent implementation of the user space component and shared logging between user and kernel space. A technique is defined for prefetching responses to HTTP GET requests using earlier GET responses. Classifying of handler extensions according to latency in deriving a response to a network request is defined. Tight integration with the file system cache is available for sending non-paged responses from the file system cache to the remote client. A complete caching scheme is defined for protocols serving file contents to remote clients.
