This is controlled by the Options directive with the Indexes option in Apache:http://httpd.apache.org/docs/2.2/mod/core.html#options
Please edit your PASE Apache configuration to prevent access by index. From a 5250 command line:
Find this in the file:
# This should be changed to whatever you set DocumentRoot to.
and then there are a few comments, and then this:
Options Indexes FollowSymLinks
Put a dash in front of Indexes, like this:
Options -Indexes FollowSymLinks
Use F3 to exit and save.
Next, stop and start Apache. From the 5250 command line:
Use option "5. Stop Apache server instances". Then, from the command line:
Make sure there are no jobs named ZENDCOREAP running in the subsystem. If there are, use F5 to redisplay until all of them are gone. Then use F3 to return to the menu.
Use option "4. Start Apache server instances". Once again, from the command line:
Make sure there are at least eight jobs named ZENDCOREAP running in the subsystem. Use F5 to redisplay until all of them are active.
