Proxy application with dynamic filter updating

摘要

The disclosure describes a proxy server application that supports the dynamic modification of proxy rules implemented by a proxy server. The proxy rules implemented by the proxy server specify network behaviors to be performed at various points during the handling of requests from client applications. A proxy server implements the proxy rules by processing one or more user-generated network traffic filters for managing network traffic. In an embodiment, users generate network traffic filters by creating network traffic filter source code that specify processing steps to be performed by a proxy server relative to network messages the proxy server receives. In an embodiment, user-generated network traffic filters may be added, removed, reordered, or otherwise modified in a proxy server application at runtime in order to respond to current network conditions or to achieve other desired proxy configurations.

主权项

1. A method comprising:
in a proxy server that is configured to receive requests directed toward one or more origin servers and to distribute the requests to one or more of the origin servers for processing, loading, from a data repository, one or more first network traffic filters, wherein each of the one or more first network traffic filters comprises an executable unit of computer program code specifying processing criteria and one or more actions; while the proxy server is executing and without ending execution of the proxy server, performing one or more of: loading and initiating operation of one or more second network traffic filters; removing one or more of the first network traffic filters; reordering one or more of the first network traffic filters; receiving, at the proxy server, a network message; for a particular network traffic filter of the one or more first network traffic filters, wherein the particular network traffic filter comprises particular processing criteria and one or more particular actions: determining whether the network message satisfies the particular processing criteria; in response to determining that the network message satisfies the particular processing criteria, causing the one or more particular actions to be performed; wherein the method is performed on one or more computing devices.
