Abstract
A method and system for injecting code into an existing HTML document that enables the conditional generation and incorporation of an injectable component is provided. The injection mechanism provided enables a user to display an add-on user interface component within a web page using a technique that is transparent to the normal processing within a browser application. The injection mechanism installs interceptor code as a proxy server between a client browser and a server. The interceptor code monitors all HTTP messages sent from the client browser and injects code into each HTML document that is sent from a server to the client browser. The injected code when executed by the client browser conditionally inserts HTML code into the received HTML document. The inserted HTML code is then used by the client browser to generate a new component, for example a user interface component. The code injected by the interceptor code is dependent upon the type of the browser and whether certain tags are present in the received HTML document. In addition, the code may be written in a script language, such as Javascript or VBscript.
