Methods and systems for generating and sending an XML document are described. In a specific implementation, methods and systems for responding to an XML client request utilize an XML response generator. The XML response generator responds to a client request without having to first build and save the entire response. An emitter object is provided that receives data that is gathered. The calls are made in a particular order and ensure that the hierarchical nature of the response that is being built is preserved. The emitter object translates the data that it receives into response portions that are in proper XML syntactic form.

Methods and systems for preparing extensible markup language (XML) documents and for responding to XML requests

Systems and methods for synchronizing multiple copies of data in a network environment that includes servers and clients so that incremental changes made to one copy of the data can be identified, transferred, and incorporated into all other copies of the data. The synchronization can be accomplished regardless of whether modifications to the data have been made by a client while the client is in an on-line or off-line mode of operation. The clients cache data locally as data are modified and downloaded. The caching enables the clients to access the data and allows the synchronization to be performed without transmitting a particular version more than once between a client and a server. Such elimination of redundant data transmission results in an efficient use of time and network bandwidth.

Various embodiments of the invention are directed to closely integrating functionality between an internet server and a WebDAV tool. Areas of specific focus in this document include delegation of duties between the internet server and the WebDAV tool, efficient management of a resource's content-type, support for segregation of a namespace into separate virtual roots, and determinations of whether to invoke certain processing extensions to handle requests for a given HTTP verb.

Methods and structures for parsing an Extensible Markup Language (XML) data stream are described. In the described embodiment, one or more schema modules are defined and are associated with HTTP requests that are received from a client. The schema module(s) has a function that determines whether an XML data stream conforms to a given schema that is associated with the HTTP request. If a portion of the XML data stream does not conform to the given schema, then the schema module disregards that XML data stream portion. In the described embodiment, each schema module has a plurality of states associated therewith. Each state is associated with one or more schema requirements that relate to a particular element that is evaluated by the schema module. Each state is different from the other states and the number of states is a function of the number of layers or elements that are contained within a particular XML data stream.

A system and method facilitating diagnostics support is provided. The system includes application(s) instrumented in accordance with a built-in diagnostics (BID) framework, and, trace component(s). The trace component can selectively employ none, some and/or substantially all of the trace point(s) associated with the application. The system can facilitate instrumentation of a managed data access stack, for example, to enhance supportability of the application.

Methods and computer program products for using a front-end server to access content stored on one or more back-end servers. The front-end server receives requests for content from client systems. Back-end servers store the content, but to the client system, it appears as if the front-end server is the content's source. Upon receiving the request, the front-end server checks the validity of the request and examines a global catalog that dynamically maps client system requests to the back-end server or servers that store the requested content. In some circumstances, the content will be stored at a single back-end server and the front-end server directs the request to that server. Alternatively, a list of back-end servers storing the requested content may be generated. If so, the front-end then uses an authentication token as a key to a hash operation that is performed on the list and a single server that is capable of satisfying the request for content is identified. A given request and authentication token always identify the same server if the list of servers available for providing the requested content remains the same. The front-end server provides a single source for content requests so that client systems are not required to alter requests or invalidate local caches when content is moved from one back-end server to another. The front-end server also provides an additional level of security for back-end servers.

Routing client requests to back-end servers

A method for efficiently sending notifications over a network. A client system requests to be notified when an event occurs. A server system receives the requests and monitors for the occurrence of the event. When the event occurs a single packet using a connectionless protocol (such as User Datagram Protocol) is sent to the client to notify the client of the occurrence of the event. Using a connectionless protocol to send notification reduces the overall amount of data on the network and thus reduces network congestion and the processing capacity of the server and client. When the client system receives notification an attempt to establish a connection using as connection-oriented protocol is executed. Additional data associated with the occurrence of the event is transferred over the connection. The server may repeatedly send notification using a connectionless protocol until a connection using a connection-oriented protocol is established. The server may send notification that notifies the client of the occurrence of multiple events simultaneously within a single packet. The server may also notify multiple applications of the occurrence of an event using a single notification.

Method and system for processing HTTP requests creating a new map for an entire namespace that is associated with the request and that maps the name extension to the further content type within namespace

Methods and systems for efficiently sending notification of the occurrence of events through a firewall. A client system operating inside a firewall, attempts to receive notification of the occurrence of events from a server system operating outside the firewall. The client system attempts to receive communication from the server system using a connectionless protocol, such as UDP. If the client system receives communication using the connectionless protocol, the client system requests notification be sent using the connectionless protocol. The server system notifies the client system by sending a packet to the server system, using the connectionless protocol, when events occur. However, if the client does not receive communication using the connectionless protocol, the client requests notifications be sent using a connection-oriented protocol, such as TCP. If the client system requests notification using a connection-oriented protocol, the client system polls the server system to receive notification of the occurrence of events.

Sending notification through a firewall over a computer network

Provided are methods and systems for integrating the access controls of computer resources into a namespace or domain. For a remote user, a computer network or system is a namespace represented by a URL. In order to enforce the access controls of the computer network being accesses, a remote user is impersonated by a server of the computer system such that access requests to the resources of a system are made by the server in the security context of the remote user. By impersonating the remote user, the actual rights of the remote user are being presented to the access controls rather than the rights of the server. In this manner, the access control of the system can be enforced directly on the remote user and the access control is effectively extended to the namespace.
