Bug: Including an HTML file takes forever

When INCLUDE'ing an html document, twiki/lib/TWiki/Net.pm connects to the web server and sends an HTTP/1.1 type request. 8.1.2.1 of the HTTP/1.1 spec states that the server may keep the connection open unless the request header contains a "Connection: close" line.

If this header is not sent, twiki hangs reading the response until the connection eventually times out, which can take 20 seconds or more.

The solution is to add the line: $req .= "Connection: close\r\n"; to the request before sending it to the web server.

Test case

%INCLUDE{"http://some.server/with/persistent/connections"}%

Fix record

I've applied the patch supplied by MS in ProxiedIncludesBrokenImplementationBug to CVS. Whilst a different solution to the one above, I expect it will solve the reported problem. I've therefore marked this a BugResolved. If it isn't fixed, then please move back to BugReport.
