⚡️ Speed up method SessionRedirectMixin.should_strip_auth by 10%

[codeflash-ai]

📄 10% (0.10x) speedup for SessionRedirectMixin.should_strip_auth in src/requests/sessions.py

⏱️ Runtime : 15.2 milliseconds → 13.9 milliseconds (best of 162 runs)

📝 Explanation and details

To optimize the given Python program for better performance, here's how we can rewrite the code to minimize redundant operations and potentially avoid some unnecessary function calls. We will focus on caching values and restructuring the flow for efficiency.

Optimizations Made.

1. Cache Computations: Cached repetitive calls to attributes like hostname, scheme, and port into variables to avoid multiple attribute accesses.
2. Minimizing Conditional Checks: Streamlined the logical checks by reducing the number of conditions evaluated. This way, we avoid additional checks if an early return condition is met.
3. Handle Default Ports Efficiently: Evaluated the default port based on the scheme only once per parsed URL.

These changes help reduce unnecessary computations and attribute accesses, thus enhancing performance.
