Function Documentation

static bs_status check_for_http_errors	(	apr_socket_t *	sock,
		http_header_info *	info,
		apr_pool_t *	mp
	)			[static]

Check to see if the right information was provided along with the HTTP headers. Use the http_header_info struct for this. Send an appropriate error message back through the socket.

Here is the call graph for this function:

static bs_status get_remaining_content	(	apr_socket_t *	sock,
		char **	result,
		const char *	initial,
		unsigned	size,
		bs_uint64	remaining,
		apr_pool_t *	mp
	)			[static]

Try to receive the remaining content from the given socket. Put the initial result and the rest of the received data in the result buffer. Return status code about the whole process. If the desired content size is just to big (see setting.h) return an eror through the socket.

bs_status handle_http_get	(	apr_socket_t *	sock,
		apr_pool_t *	mp
	)

Handle a HTTP GET request by simply outputting an HTML status page. This page is the banner.html file included in the daemon directory by default.

Parameters:

	sock	Socket to use
	mp	Memory pool to allocate from

Returns:

Status code.

Here is the call graph for this function:

bs_status handle_http_post	(	apr_socket_t *	sock,
		const char *	headerbuf,
		apr_size_t	headerlen,
		apr_pool_t *	mp
	)

Handle a HTTP POST request by assuming it contains an XML request for a service. First the HTTP headers are interpreted, then the xml payload is translated into an internal data structure (

See also:

bs_service_request). This request is then serviced and the resulting response is translated to xml and send back to the caller (

bs_service_response).

Parameters:

	sock	Socket to use
	headerbuf	Buffer containing HTTP headers and (part) of the xml data
	headerlen	Length of the buffer
	mp	Memory pool to allocate from

Returns:

Status code.

bs_status send_http_error	(	apr_socket_t *	sock,
		const char *	errstring,
		apr_pool_t *	mp
	)

Send an HTTP message through the socket indicating an error.

Parameters:

	sock	Socket to use (not closed by this function)
	errstring	The error string to send (ie. HTTP 404 Not Found)
	mp	Memory pool to allocate from

Returns:

Status code.
