A method and system that provide an accessibility gateway to the Internet through the use of a web intermediary server, which may belong to a different domain than the web content server. The web intermediary server includes server-generated applications for modifying accessibility settings for supported client devices, registering the user for authority to use the intermediary server services, and generating web-based, user-specific browser service replacements such as history lists and bookmarks. A request for any web page is sent from the client device to the intermediary server. The intermediary server retrieves the requested web document, and applies user-defined transformations to the web document, which is then sent back to the user device's user agent. If the web document is from a secure web page, the intermediary server functions as a proxy for the user device to establish the requisite secure connection with the web page.
