Good C code will try to avoid allocations as much as possible in the first place. You absolutely don’t need to copy strings around when handling a request. You can read data from the socket in a fixed-size buffer, do all the processing in-place, and then process the next chunk in-place too. You get predictable performance and the thing will work like precise clockwork. Reading the entire thing just to copy the body of the request in another location makes no sense. Most of the “nice” javaesque XXXParser, XXXBuilder, XXXManager abstractions seen in “easier” languages make little sense in C. They obfuscate what really needs to happen in memory to solve a problem efficiently.
