Handling of expired web pages

A non-transitory machine readable medium storing one or more sequences of instructions for causing a content server to serve content on a network, wherein execution of said one or more sequences of instructions by one or more processors contained in said content server causes said content server to perform the actions of:

• receiving a request for a static web page from a client system;
• retrieving a content of said static web page from a secondary storage, said content having an associated date of expiry;
• determining whether said content of said static web page is valid, wherein both of said determining and said retrieving are performed after said receiving,
• wherein said determining comprises comparing a current time with said date of expiry of said content, said content being determined as not being valid if said current time is later than said date of expiry, and valid otherwise;
• and
• if said content is determined as being valid, sending said static web page, including said content, to said client system as a response to said request,
• else, sending additional content along with said content of said static web page to said client system as said response to said request,
• wherein said additional content causes display of a message indicating that the content of said static web page is not valid, on said client system when said content of said static web page is displayed on said client system as a response to said request for said static web page.

A computing system comprising:

• a non-volatile storage to store a static web page and an associated expiry date, said static web page containing a content for rendering on client systems;
• and
• a web server to receive a request for said static web page from a client system on a network based on Internet Protocol (IP), and in response, to retrieve said static web page and said associated expiry date from said non-volatile storage, wherein said request is received at a current time,
• said web server to determine that said content has expired if said current time is after said associated expiry date and not expired otherwise,
• said web server being addressable by an IP address on said network, wherein said request is directed to said web server in that the request is received from said client system in the form of an IP packet, said IP packet having a destination address set to said IP address of said web server when originating at said client system.
