[Bruce Hamilton (bjhham)]

Subsystem
Server, Routing

Motivation
Improve request memory allocations in complex routing logic.

Solution

• Introduced a fast path trie lookup for matching on simple path matchers
• Added internal blocking evaluate method to avoid allocating unnecessary continuations
• Added deferred path split string wrapper to avoid allocating unnecessary list on url path
