From 475ee7b55a24ed6a17e0bb5ef762560ebb0ab152 Mon Sep 17 00:00:00 2001 From: Holger Weiss Date: Sat, 21 Jul 2007 16:29:01 +0000 Subject: Add "Connection: close" to the HTTP request header, which tells HTTP/1.1 servers to close the connection after completion of the response. This should be compatible with HTTP/1.0, as HTTP/1.0 allows for custom header fields which should be ignored if not recognized by the server. With some server configurations, the server would keep the connection alive without this header line (despite the plugin requesting HTTP/1.0), resulting in the plugin running into either the server's or it's own timeout (reported by Roman Schliessmeyer and Jesse Morgan via IRC). git-svn-id: https://nagiosplug.svn.sourceforge.net/svnroot/nagiosplug/nagiosplug/trunk@1759 f882894a-f735-0410-b71e-b25c423dba1c --- plugins/check_http.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'plugins') diff --git a/plugins/check_http.c b/plugins/check_http.c index 26a074df..b371cd64 100644 --- a/plugins/check_http.c +++ b/plugins/check_http.c @@ -782,6 +782,9 @@ check_http (void) asprintf (&buf, "%s %s HTTP/1.0\r\n%s\r\n", http_method, server_url, user_agent); + /* tell HTTP/1.1 servers not to keep the connection alive */ + asprintf (&buf, "%sConnection: close\r\n", buf); + /* optionally send the host header info */ if (host_name) asprintf (&buf, "%sHost: %s\r\n", buf, host_name); -- cgit v1.2.3-74-g34f1
