Abstract
Disclosed are systems and methods for performing consistent request distribution across a set of servers based on a request Uniform Resource Locator (URL) and one or more cache keys, wherein some but not all cache keys modify the content requested by the URL. The cache keys include query string parameters and header parameters. A request director parses a received request, excludes irrelevant cache keys, reorders relevant cache keys, and distributes the request to a server from the set of servers tasked with serving content differentiated from the request URL by the relevant cache keys. The exclusion and reordering preserves the consistent distribution of requests directed to the same URL but different content as a result of different cache key irrespective of the placement of the relevant cache keys and inclusion of irrelevant cache keys in the request.
