Overview

Automatically integrate TLS session cache (ClientSessionCache) with retryablehttp for improved performance.

Details

• Add shared LRU session cache to HTTP client TLS configurations when creating or wrapping HTTP clients
• Should work transparently with new HTTP clients or any provided ones if absent
• Reduces TLS handshake overhead and CPU usage for repeated connections to the same host
• Improves overall throughput and efficiency
• Should be a clean, transparent optimization that doesn't change behavior

Benefits

• Lower CPU usage from reduced TLS handshakes
• Better performance for scenarios with repeated connections to the same hosts
• No breaking changes or compatibility issues
