static char *	ngx_http_limit_proxy (ngx_conf_t *cf, ngx_command_t *cmd, void *conf)
	Called if module is to be enabled. Overrides old module handle and saves it. Sets conf->enable to 1.

	Creates module configuration.
static char *	ngx_http_limit_proxy_merge_loc_conf (ngx_conf_t *cf, void *parent, void *child)
	Merge module configuration, allocate connection pool. Sockaddr structure will also be created.
static void	ngx_limit_proxy_dummy_handler (ngx_event_t *ev)
	Used to fill write and read handler when not needed. Should never be called anyway.
static ngx_buf_t *	ngx_http_limit_proxy_create_question (ngx_http_request_t *request)
	Create query to ask server about user access. Fetchs headers from request.
static void	ngx_http_limit_proxy_write_handler (ngx_event_t *write_event)
	Write handler, sends next portion of data (if any). When all data are send, removes write event.
static ngx_int_t	ngx_http_limit_proxy_reject (ngx_http_request_t *r)
	Send access deined message.
static void	ngx_http_limit_proxy_read_handler (ngx_event_t *read_event)
	Read handler - reads data and redirects client.
