Really? You can't see what's wrong there?
Your rewrite rule says to look for the URLs beginning with '/olat/'
and you went to '/olat'.
You shouldn't be using rewrite to initiate proxying unless your
situation is strange or bizarre - and if you have control over your
situation, don't make it strange or bizarre.
Also, your question reminds me of an english saying:
Patient: Doctor, it hurts when I do this: *patient waves his arm around*
Doctor: Don't do that then....
You have it working in the correct manner, and then break it and say
woe is me :/
Cheers

Here you are saying about the / at the end is that what you mean?

When a request comes for /olat/ then it gets proxied to PR:
http://192.168.1.5:8080/olat/
and via RR it goes to PR: http://192.168.1.5:8080/olat
in this case I do not get the difference.
The url has a / at the end in PR so in RR also I should have a /
as you mentioned below

Here why it tries to serve from DocumentRoot Not clear with this?

Re: [users@httpd] ProxyPass work correctly but ReWriteRule has some

Look at your configuration again. First, ProxyPass
ProxyPass /olat http://192.168.1.5:8080/olat
ProxyPassReverse /olat http://192.168.1.5:8080/olat
This says, when someone requests a URL starting with '/olat', proxy to
'http://192.168.1.5:8080/olat'
It also says to rewrite some headers, but thats not important right now.
Now, your RewriteRule version:
RewriteRule ^/olat/ http://192.168.1.5:8080/olat [P,L]
This says, when someone requests a URL that begins with '/olat/',
proxy to 'http://192.168.1.5:8080/olat'
Can you really not see the difference?
Let me show you with some URLs, and show what they get proxied to in
each version. PR = Proxy rule, RR = Rewrite
URL: /olat/
PR: http://192.168.1.5:8080/olat/
RR: http://192.168.1.5:8080/olat
URL: /olat/media/base.css
PR: http://192.168.1.5:8080/olat/media/base.css
RR: http://192.168.1.5:8080/olatmedia/base.css
URL: /olat
PR: http://192.168.1.5:8080/olat
RR: None, attempts to serve the file /olat from your document root
I hope you can understand why now.
Cheers
Tom

Yes I am not clear with ReWriteRule.

That is how olat works
when some one types in browser
http://mydomain.com/olat
then they get a page
http://mydomain.com/olat/index.php
or some other pages I do not know what exactly has been programmed in
OLAT (I downloaded it from internet)

I am trying to understand how where can ReWriteRule be used and where
ProxyPass is used.
So I want to know what is the mistake.
