Url Rewrite different domain

this is my environment:

- my main domain is : http://example.azure.com

- my other service domain is : http://myapp.azure.com 

the situation is, i want add the app to http://example.azure.com/myapp that rewrite the url to http://myapp.azure.com (so the url didn't change, still http://example.azure.com/myapp)

but the problem is, i got stylesheet / javascript error that rewrite the original url becomehttp://example.azure.com/ this is my error of console log 

http://example.azure.com/components/jquery-ui/themes/smoothness/jquery-ui.min.css Failed to load resource: the server responded with a status of 404 (Not Found)

because the /components is located on url http://myapp.azure.com/components.... 

how to solve it?

thanks you
