Highlights
🍪 Faster requests with large cookie jars
Building the Cookie header no longer scans every cookie in the jar. The client reuses its jar instead of copying it on every request and redirect (#1284), only looks up the domains that can match the request host, and skips the expired cookie sweep until a cookie is due (#1285). With 1,000 cookies across 500 domains, building the Cookie header is about 18 times faster.
Cookies from different domains are now sent from the least to the most specific domain, for example .example.org before sub.example.org, instead of in the order the domains were added. Cookies with longer paths still come first.

Changed
- Look up only the cookie domains that match the request host, and skip the expired cookie sweep until a cookie is due. With 1,000 cookies across 500 domains, building the
Cookieheader is about 18 times faster. Cookies from different domains are now sent from the least to the most specific domain (#1285).
Fixed
- Reuse the client cookie jar instead of copying it on every request and redirect. A custom policy set with
client.cookies.jar.set_policy()now applies to outgoing requests (#1284).
