Abstract
Abstract An error handler for a proxy server computer system receives a universal resource locator from a remote user terminal, accesses from a computer network a data file identified by the universal resource locator for supply to the user terminal, automatically modifies the universal resource locator in response to detection of a failure by the accessing means to access the data file, determines if a data file identified by the modified universal resource locator is accessible to the user terminal, and returns variable data indicating the error and offering remedial options to the user.

Claim 1
Independent Claim
92 words
An error handler for a proxy server computer system, the error handler comprising: means for receiving a universal resource locator from a remote user terminal; means for accessing from a computer network a data file identified by the universal resource locator for supply to the user terminal; means for automatically modifying the universal resource locator in response to detection of a failure by the accessing means to access the data file; and, means for determining if a data file identified by the modified universal resource locator is accessible to the user terminal.
Claim 2
Dependent Claim
92 words
