When trying to save Aliases and Redirects for Apache server, webmin complains produces error: Failed to save Aliases and Redirects : 'ajp://localhost:8009/myapp' is not a valid remote URL.
Only way to save config is to use "Edit Directives" with the valid syntax:
ProxyPass /myapp ajp://localhost:8009/myapp
This is the correct syntax for mod_proxy_ajp.
Problem occurs in 1.520 and 1.700 of webmin
Thanks - this will be allowed in Webmin 1.710.
