Hi,
There are so many good features are available in apache, those are beneficial
for different aspects:
1. Load balancing:
User requests are processed by more than one server with all servers
sharing the load 'equally'
2. Transparent failover:
User is not aware of a server crash.
or Prefork? This can be obtained with
apachectl -V

You can configure server itself to add this trailing slash.
For example if you configured it as

Then your request on browser must be ../saleslead/ like that
If I replace it by

Then why the warning when I don't have the trailing /?
