Creating public sparql endpoint with fuseki problem

Hi, I have tried to create public sparl endpoint but I didn't. Downloaded
fuseki to C:\temp (C:\temp\jena-2.12.0\jena-fuseki) and start fuseki with
"fuseki-server --update --mem /ds" command. I put my data (aaa.ttl) on
"C:\temp\jena-2.12.0\jena-fuseki" directory only and give a s-put command
"ruby s-put http://localhost:3030/ds/data default aaa.ttl". It made my data
ready for querying both command prompt and localhost:3030 control panel
directory. http://site/sparql my sparql endpoint and it pass request to
http://localhost3030/dataset/query. For creating public sparql endpoint, apache
reverse proxy configuration must be done. So I created a ".htaccess" folder
at htdocs directory in Apache with the following statements (and I also
change some of the httpd.conf setting off to on ):

RewriteRule ^/sparql$ C:\temp\jena-2.12.0\jena-fuseki\pages\sparql.html [L]

RewriteCond %{QUERY_STRING} query=
RewriteRule . http://localhost:3030/dataset/query
<http://localhost:3030/ds/query> [P]

But it didn't work. "http://localhost:3030/dataset/query
<http://localhost:3030/ds/query>" gives "Error 404: Service Description".
How can I solve this problem and create public sparql endpoint? Is there
any way to make reverse proxy except for apache or nginx? Could you please
tell step by step? Thanks a lot
