Redirection problem with mod ajp

hi all i have a redirection problem with mod ajp, that it always adds the application name before the desired page, for example:

if i requested the page:

http://myapp.com/mypage

it is converted to

http ://myapp.com/myapp/mypage, and i get a 404 error

i don’t know why such behaviour occurs, this is the configuration:

<Proxy *> AddDefaultCharset Off Order deny,allow Allow from all </Proxy> 
ProxyPass / ajp://127.0.0.1:8009/myapp/ 
ProxyPassReverse / 
ajp://127.0.0.1:8009/myapp/ 
ProxyPassReverseCookiePath /myapp/ 

this strange redirection occurs exaclty when an inside application redirection occurs meaning after registration the user is redirected(application side) to the login page using response.sendRedirect , any ideas ?
