User interface that provides relevant alternative links

A system comprising:

• an error code receiver communicatively connected to a context analyser of the type that responds to a second web page not being sent to a web browser following a selection of a link on a first web page due to the link being a broken link, said link specifying the second web page, and which is configured to receive information identifying the first web page from an error code receiver, analyse at least a location of the link on the first web page and at least one or more keywords in a vicinity of the location of the link on the first web page but less than the entire first web page to determine information regarding the context of the link specifying the second web page and thereby deduce information regarding the context of the second web page, establish a list of one or more web pages that are relevant to the context of the second web page on the basis of the so determined information regarding the context of the link specifying the second web page, and communicate the list to a response generator, the response generator being operable to generate a response based on the list and to communicate the response to the web browser, the error code receiver being arranged to receive, in at least one computing device comprising a processor configured by executing software instructions stored in a memory, a hypertext transfer protocol (HTTP) error code from an error detector, wherein the HTTP error code is indicative that, following the selection of the link on the first web page specifying the second web page, the second web page was not sent to the web browser;
• the error code receiver being arranged to cause, in the at least one computing device, in response to receiving the error code, information identifying the first web page to be sent to the context analyser.

A server computer for modifying the behaviour of a proxy server, the server computer being communicatively connected to a context analyser of the type that responds to a second web page not being sent to a web browser following a selection of a link on a first web page due to the link being a broken link, said link specifying the second web page, and which is configured to receive information identifying the first web page from an error code receiver, analyse at least a location of the link on the first web page and at least one or more keywords in a vicinity of the location of the link on the first web page but less than the entire first web page to determine information regarding the context of the link specifying the second web page and thereby deduce information regarding the context of the second web page, establish a list of one or more web pages that are relevant to the context of the second web page on the basis of the so determined information regarding the context of the link specifying the second web page, and communicate the list to a response generator that is operable to generate a response based on the list and to communicate the response to the web browser, comprising:

• a processor configured by executing software instructions stored in a memory,
• a communication means for transferring messages between the server computer and a proxy server, wherein the communication means is operable to transfer Internet Content Adaptation Protocol (ICAP) messages;
• and
• the error code receiver, arranged to:
• receive, in at least one computing device, an error code from an error detector, wherein the error code is indicative that, following the selection of the link on the first web page specifying the second web page, the second web page was not sent to the web browser;
• cause, in the at least one computing device, in response to receiving the error code, information identifying the first web page to be sent to the context analyser;
• and
• wherein the error code receiver is operable to analyse messages to determine whether a message contains the error code.

A method of providing a user with a user interface responsive to a second web page not being available to be sent to a web browser following a selection of a link on a first web page, said link specifying the second web page, the method comprising the steps of:

• selecting the link on the first web page specifying the second web page;
• detecting that the second web page as requested by the web browser is not available to be sent to the web browser due to the link being a broken link and, in response, generating a hypertext transfer protocol (HTTP) error code;
• receiving the HTTP error code and, in response, analyzing at least a location of the link on the first web page and at least one or more keywords in a vicinity of the location of the link on the first web page but less than the entire first web page to determine the context of the selected link and thereby deduce the context of the second web page and thereby establishing a list of one or more web pages that are relevant to the context of the second web page and may be of interest to the user on the basis of the so determined information regarding the context of the link specifying the second web page, and
• generating a response based on the list and communicating the response to the user.

A system responsive to a second web page being inaccessible following a selection in a web browser of a link on a first web page, said link specifying the second web page, comprising at least one computing device comprising a processor configured by executing software instructions stored in a memory, an error code receiver executable in the at least one computing device, a context analyser executable in the at least one computing device and a response generator executable in the at least one computing device, wherein:

• the error code receiver is operable to receive a hypertext transfer protocol (HTTP) error code and, in response, cause information to be sent to a context analyser, the HTTP error code being indicative of the selection in the web browser of the link on the first web page specifying the second web page and the second web page being inaccessible due to the link being a broken link and the information including information identifying the first web page;
• the context analyser being operable to:
• receive the information from the error code receiver, analyse at least a location of the link on the first web page and at least one or more keywords in a vicinity of the location of the link on the first web page but less than the entire first web page to determine information regarding the context of the link and thereby deduce the context of the second web page, establish a list of one or more web pages that are relevant to the context of the second web page on the basis of the so determined information regarding the context of the link specifying the second web page, and communicate the list to a response generator;
• and
• the response generator being operable to generate a response based on the list and to communicate the response to the web browser.

A system responsive to a second web page being inaccessible following a selection of a link on a first web page, said link specifying the second web page, comprising a processor configured by executing software instructions stored in a memory, an error code receiver, a context analyser and a response generator, wherein:

• the error code receiver is operable to intercept a hypertext transfer protocol (HTTP) error code sent from a server computer to a client computer and, in response, cause information to be sent to a context analyser, the HTTP error code being indicative of the selection, at the client computer, of the link on the first web page specifying the second web page and the second web page being inaccessible and the information including information on the first web page;
• the context analyser being operable to:
• receive the information from the error code receiver, analyse at least a location of the link on the first web page and at least one or more keywords in a vicinity of the location of the link on the first web page but less than the entire first web page to determine information regarding the context of the link and thereby deduce the context of the second web page, establish a list of one or more web pages that are relevant to the context of the second web page on the basis of the so determined information regarding the context of the link specifying the second web page, and communicate the list to a response generator;
• and
• the response generator being operable to generate a response based on the list and to communicate the response to the client computer.
