Synchronizing structured web site contents

A computer implemented method for synchronizing structured web site contents, the method comprising:

• receiving, by a server, a client content list from a client;
• retrieving a server content list;
• comparing, by at least one processor at the server, the client content list and the server content list;
• determining structured content types supported by the client and by the server;
• generating a shared content list based on the determination of structured content types supported by the client and by the server;
• sending the shared content list to the client;
• receiving, from the client, a request to synchronize one or more structured content types in the shared content list, wherein the request comprises a limit on a number of items to be returned;
• and
• performing one or more synchronization operations based on the received synchronization request, wherein the received request with the item limit causes the server to pass a parameter into a list query to limit the number of items returned to the item limit, and wherein any delete operations are excluded from the item limit.

A system for synchronizing structured web site contents, the system comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor, the memory comprising computer-program instructions executed by the at least one processor for:
• transmitting, by a client device, a request for a server content list, wherein the server content list comprises one or more structured content types supported by a server device, and wherein the one or more structured content types comprise one or more from the group consisting of:
• calendar, contact, discussion, document, and tasks;
• receiving, by the client device, the server content list;
• comparing the server content list with a client content list, wherein the client content list comprises one or more structured content types supported by the client device;
• identifying, by the client device, one or more structured content types shared by the client device and by the server device;
• receiving, by the client device, a synchronization interval parameter, wherein the synchronization interval parameter is based on historical content change data;
• transmitting, by the client device, a first synchronization query to synchronize the one or more shared structured content types, wherein the synchronization query comprises a change token and a maximum number of items to be returned, and wherein the items to be returned are the items that have changed since a value of a change token, and wherein the first synchronization query uses a paging technique;
• when more than the requested maximum number of items has changed:
• receiving, by the client device, a first number of items up to the maximum number of items and the change token;
• receiving, by the client device, a value for requesting a next number of items up to the maximum number of items from a start of the value;
• and
• transmitting, by the client device, a second synchronization query, wherein the second synchronization query comprises the change token and the value, and wherein the second synchronization query uses the paging technique.
