Shared HTTP Client Session Pool for Process Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing systems face substantial costs and latency due to the need for multiple HTTP client sessions to be initiated for each application process communicating with remote servers, especially when using secure protocols like HTTPS, and managing these sessions across multiple application processes is inefficient, leading to overhead and potential failures.
Innovation Solution
Implementing a shared pool of pre-established HTTP client sessions managed by the operating system, allowing any application process to use these sessions directly without an additional HTTP client process, thereby eliminating the need for inter-process communication and reducing the overhead of session initiation and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple HTTP client sessions are initiated for each application process, then each process can communicate independently with remote servers, but system cost and latency increase substantially
Solution Approach 1:
Multiple application processes share a common pool of HTTP client sessions managed by the operating system, merging previously separate session resources into a shared pool that multiple processes can access simultaneously, thereby reducing redundant session initiations and lowering latency
Solution Approach 2:
HTTP client sessions are pre-established and maintained in a shared pool before being needed by application processes, allowing processes to immediately use existing sessions rather than initiating new ones, thus eliminating session initiation latency
2Ease of operation
If separate HTTP client processes are used for each application process, then session management is simplified, but system overhead and complexity increase
Solution Approach 1:
The operating system's process management mechanisms are extended to universally manage HTTP client sessions for multiple application processes, allowing the same OS infrastructure to handle both process control and session management, thereby eliminating the need for separate HTTP client processes and reducing system overhead
Solution Approach 2:
Application processes directly access and use HTTP client sessions from the shared pool without requiring an intermediate HTTP client process, allowing processes to self-manage their own session usage through direct OS interface, thus eliminating unnecessary process layers and reducing complexity
3Productivity
If HTTP client sessions are shared across multiple application processes, then resource utilization improves and overhead is reduced, but session management complexity increases
Solution Approach 1:
The operating system acts as an intermediary between application processes and HTTP client sessions, providing a centralized management layer that handles session allocation, tracking, and coordination, thereby enabling efficient sharing across multiple processes while keeping management logic centralized and manageable

AI summary
Technical solutions are described for sharing HTTP client sessions among multiple processes being executed by a client computing device. An example method includes creating a set of HTTP client sessions for a remote server. The method further includes, in response to receiving an HTTP request from an application process, the HTTP request is for communicating with the remote server, assigning an HTTP client session from the set of HTTP client sessions to the application process, and sending the HTTP request from the application process to the remote server via the HTTP client session that is assigned. The method further includes, in response to receiving a reply from the remote server, deselecting the HTTP client session from the application process, and sending the reply from the remote server to the application process.
