Error messaging method in http based communication systems

摘要

The invention relates to error messaging in HTTP based communication systems. An intermediate device ( 20 ) interconnecting a wireless client terminal ( 10 ) and a web server ( 30 ) transforms error messages sent from the server before transmitting them to the client. Hereby, a first error status code from the server is transformed into an error description message comprising an error description text and a second status code. The second status code preferably enforces display of the error description text at the client terminal. The invention is with advantage implemented in a proxy server ( 20 ) through an error information table ( 22 ) providing resource-location dependent error messages.
