- [section Custom Parsers]
- While the parsers included in the library will handle a broad number of
- use-cases, the __basic_parser__ interface can be subclassed to implement
- custom strategies for storing parsed results: the basic parser processes
- input buffers into elements according to the HTTP/1 protocol specification,
- while the derived class decides what to do with those elements. Custom parsers
- will work with all of the HTTP stream read algorithms, as those algorithms use
- only the basic parser interface. Some use cases for implementing custom
- parsers are:
- * Inspect incoming header fields and keep or discard them.
- * Use a container provided by an external interface.
- The basic parser uses virtual functions. To declare your user-defined parser,
- derive from __basic_parser__ and implement all the required virtual functions.
- A declaration for the derived class may look like this:
- [code_http_10_custom_parser]
