void ola::http::HTTPServer::RegisterDefaultHandler

(

BaseHTTPCallback *

handler

)

Set the default handler.

Parameters

handler

the default handler to call. This will be freed when the HTTPServer is destroyed.

bool ola::http::HTTPServer::RegisterFile	(	const std::string &	path,
		const std::string &	content_type
	)
