Web Access Management System

A web access management system comprising:

• a memory arranged to store a data access structure the inputs of which comprise position identifiers and access tokens;
• an analyser arranged to measure the load of a web server the access to which is managed by the access management system, and to periodically determine a queue activation condition, and a queue access release condition with a corresponding number of accesses;
• and
• a distributor arranged to receive a request to access a web page from a client browser, and, when the queue activation condition is positive, to test if this request to access a web page has a valid access token, to make it possible to access the web page concerned if the access token is valid, and, if the access token is not valid, to return to the client browser a waiting web page comprising a position identifier specific to the client browser and indicating its position in the queue, and to store this position identifier in the access data structure without matching it with an access token,
• the analyser being arranged, in the event of a queue access release condition, to extract from the access data structure position identifiers such that the positions in the queue that they indicate are the oldest and the number of which is equal to the corresponding number of accesses of the queue access release condition, to generate for each position identifier a valid access token, and to store each valid access token matching the position identifier for which it was generated in the access data structure, and
• the waiting page web comprising a JavaScript code inducing a periodic page reloading as well as a position identifier request in the access data structure, and, in the event of receipt in response of a valid access token, to trigger a new request to access a web page with the valid access token.
