I have got a problem while uploading files on my server, when i am trying to upload files using Internet Protocol of my server. It is working fine but when i am trying to upload same files from my domain name. It is not working.

my application is deployed on Apache tomcat 7.0 on Linux machine.

Server.xml

<Connector port="8080" protocol="HTTP/1.1"
           connectionUploadTimeout="36000000" 
           disableUploadTimeout="false"
           connectionTimeout="6000000"
           maxPostSize="0"
           redirectPort="8443" 
           />
