A method, system and computer program product for facilitating inter-proxy communication via an existing protocol. A proxy receives a message (e.g., request message) using a protocol, such as HTTP. If the proxy determines to add proxy relevant information to the message, then the proxy defines a new message header for the inter-proxy communication, which is added to the existing header section of the message. The proxy relevant information is then added in the newly added message header of the message. The message with the proxy relevant information is then transmitted to a subsequent proxy using the protocol of the underlying request-response transaction. In this manner, inter-proxy communications are enabled via an existing protocol (e.g., HTTP) that is used in the request-response transaction so that proxies can communicate with one another pertaining to matters (e.g., maintenance schedule) unrelated to the original intent of the transaction using the existing protocol (e.g., HTTP).

Facilitating inter-proxy communication via an existing protocol

A proxy is modified, to form an enhanced proxy, wherein the proxy is configured to inspect a header portion of a Hypertext Transfer Protocol (http) message, the modifying enabling the enhanced proxy to identify, at the enhanced proxy, a set of http header types in the http message received from a system. An external licensing authority (LA) is modified, to form an enhanced LA, wherein the enhanced LA is configured to verify a header parameter corresponding to a header type in the set of header types and return a license information corresponding to the system. The http message is modified by modifying the header portion in the http message according to the header type and a threshold corresponding to the header type, the header type and the threshold being identified in the license information. The modified http message is transmitted.

Managing content delivery and content usage for client devices can include receiving, using computer hardware, HyperText Markup Language (HTML) code from a content server, wherein the HTML code is sent in response to a request originating from a client device, sending to an HTML licensing server, using the computer hardware, a query specifying the content server and a list including an HTML construct detected in the HTML code, receiving from the HTML licensing server, using the computer hardware, HTML license information specifying a validity status for the HTML construct on the list and a period of time for which the validity status is active, and determining, using the computer hardware, that the HTML code is invalid based on a current time, the validity status of the HTML construct, and the period of time.

Provided are techniques for real-time cookie format validation and notification. It is determined that a web page with the real cookie is loaded onto a browser at a client. In response to determining that a control cookie does not exist for the real cookie, a matching cookie pattern for the real cookie is searched for in a cookie patterns database. In response to determining that the matching cookie pattern has been found for the real cookie, the control cookie is created. In response to determining that the matching cookie pattern has not been found for the real cookie, a notification is provided that the real cookie does not have a conforming format.
