<strong>Apache</strong> <strong>HTTP</strong><br />

<strong>Server</strong> <strong>2.4</strong><br />

<strong>Problem</strong><br />

<strong>Diagnosis</strong><br />

Jeff Trawick<br />

Introduction<br />

What kinds of<br />

issues<br />

encountered<br />

Using tools<br />

inside the web<br />

server<br />

Looking from<br />

the outside<br />

What if you<br />

build the code<br />

differently<br />

Compare with<br />

httpd 2.2 and<br />

nginx<br />

mod whatkilledus and mod backtrace actually work well<br />

on Windows, with great backtraces if the web server .pdb<br />

files are available.<br />

The original versions of mod whatkilledus and<br />

mod backtrace worked somewhat differently:<br />

mod backtrace and mod whatkilledus acted independently.<br />

Neither supported Windows, and mod backtrace supported<br />

fewer Unix-y platforms.<br />

mod whatkilledus had no mechanism to filter out sensitive<br />

information.<br />
