Configurable and dynamic transformation of web content

Dynamically transforming web content is described. An HTTP request is received from an Internet client. The web resource identified in the HTTP request is accessed. The content of the web resource is analyzed. A set of transformation instructions are applied on a set of identified portions of the content of the web resource. Each applied transformation instruction includes logic to locate and manipulate at least an identified portion of the content, and at least one of the applied transformation instructions is a client-side script transformation instruction that performs one or more of: modify a client-side script included in the content, remove a client-side script included in the content, and add a client-side script to the content. An HTTP response is rendered that includes the results of the applied transformation instructions and further includes those portions of the content that were not manipulated by a transformation instruction. The response is then transmitted to the Internet client.
