Functionality available on an enterprise server is applied to HTML content from a remote server. HTML content is collected from remote servers including remote markup tags upon request from an end user. The HTML content for the remote markup tags is parsed and converted to content formatted for enterprise server functionality. The converted content is executed at the enterprise server. Remote server and enterprise server data are then transmitted to the end user. Tags and/or libraries may be extensible, such that they may be created or modified, and the tags may or may not be included within a supplied library of tags and/or a created library of tags, or any combination thereof.
