This application relates generally to automated systems and methods for identifier propagation across uniform resource locator requests. In an embodiment, a system includes at least one processor operatively coupled with a datastore, the at least one processor configured to receive, from a user device, a request message comprising a request component uniform resource locator. The at least one processor is further configured to produce a redirect uniform resource locator in response to the request message not comprising a session identifier, where the redirect uniform resource locator comprises a current session identifier appended to the request component uniform resource locator. The at least one processor is further configured to send, to the user device, a redirection instruction comprising the redirect uniform resource locator, where the redirection instruction indicates that a resource requested by the request message has been temporarily moved to the redirect uniform resource locator.
