I'm having trouble setting up a secret between Apache (2.4.41) and Tomcat (7.0.99). I think I have it setup correctly in Tomcat (server.xml):

<Connector ... secretRequired="true" secret="123" />

When I try to setup the Apache end (httpd-ajp.conf):

ProxyPass / ajp:// secret="123"

Apache fails to start and the Apache error log says:

AH00896: failed to make connection to backend:


AH00957: AJP: attempt to connect to

If it makes any difference, I'm using XAMPP for Windows 7.3.13

mod_proxy_ajp didn't support the secret option before Apache 2.5.

    The docs says it is available from 2.4.42, but it is not released yet. Is there any way to know when it is supposed to be released?

    @Viraj don't put quotes around the secret, i.e. ProxyPass / ajp:// secret=123 Sep 16, 2020 at 18:01
  • also there need to be a space before the secret. However it takes you to the TC manager, how to you configure to go directly to an app as root, www.mysite.com with /mysite on TC?
