clientSetKeepaliveFlag()

void clientSetKeepaliveFlag

(

ClientHttpRequest *

http

)

clientSetKeepaliveFlag() sets request->flags.proxyKeepalive. This is the client-side persistent connection flag. We need to set this relatively early in the request processing to handle hacks for broken servers and clients.

findTrailingHTTPVersion()

const char* findTrailingHTTPVersion	(	const char *	uriAndHTTPVersion,

'end' defaults to NULL for backwards compatibility remove default value if we ever get rid of NULL-terminated request buffers.

parseHttpRequest()

Http::Stream* parseHttpRequest	(	ConnStateData *	csd,
		const Http1::RequestParserPointer &	hp
	)

Parse an HTTP request

Note

Sets result->flags.parsed_ok to 0 if failed to parse the request, to 1 if the request was correctly parsed.

Parameters

[in]	csd	a ConnStateData. The caller must make sure it is not null
[in]	hp	an Http1::RequestParser
[out]	mehtod_p	will be set as a side-effect of the parsing. Pointed-to value will be set to Http::METHOD_NONE in case of parsing failure
[out]	http_ver	will be set as a side-effect of the parsing

Returns

NULL on incomplete requests, a Http::Stream on success or failure.
