Re: TraceEnable off directive not work (Apache Users)

Try removing the rewrite rules and see what you get. I've tested simply "TraceEnable Off" without the rewrites on a build of apache 2.2.27 for RHEL and it works as expected:

Trying 127.0.0.1...

Connected to localhost.

Escape character is '^]'.

TRACE /

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

<title>405 Method Not Allowed</title>

</head><body>

<h1>Method Not Allowed</h1>

<p>The requested method TRACE is not allowed for the URL /.</p>

</body></html>

Connection closed by foreign host.

The behavior is also the same in 2.2.31, which is the latest in the Apache 2.2.x branch.

Sorry, brain cramp there. Tomcat. I see.

I wonder if you've had an opportunity to try this on 2.4 httpd. 2.2.27 is from nearly 3 years ago.

Hello,

I Just experienced a weird behavior of TraceEnable directive.

Before use this directive, i use mod_rewtire to disable trace and other unwanted HTTP method. Since this directive been added, TRACE method start getting 200 return.

Ive tried both jmeter and telnet, the results are same, protection was gone.

Im running apache 2.2.27 on a Linux box, I add both TraceEnable directive along with Rewrite directives together, thought it would be “more proper way to dong this” and a double protection

related configs in http.conf as follows:

TraceEnable off

RewriteEngine on

RewriteCond %{REQUEST_METHOD} ^(TRACE|TRACK|PUT|DELETE)

RewriteRule .* - [R=405,L]

and results as follows:

TRACE / HTTP/1.1

HOST:www.domain.com.cn

HTTP/1.1 200 OK

in access_log, can clearly see

[18/Feb/2016:15:36:29 +0800] "TRACE / HTTP/1.1" 200 10219 www.domain.com.cn

after I removed this directive, just leave Rewrite directives, redirect are normal.

TRACE / HTTP/1.1

HOST:www.domain.com.cn

HTTP/1.1 405 TRACE method is not allowed

In access_log

I think this could indicates that "TraceEnable off" is bugged/not working.

Any thoughts? please advise.

Thank you

Cheers
