jsf 2 - Change /javax.faces.resource prefix of resource URLs

Question

When I use

<h:outputStylesheet library="css" name="styles.css"> 

or

<h:graphicImage library="images" name="image.jpg">

then in html I get something like this

<link type="text/css" rel="stylesheet" href="/appName/javax.faces.resource/styles.css.xhtml?ln=css" />

so the user can see which framework was used to write this app. How can I avoid showing javax.faces.resource/styles.css.xhtml?ln=css to the user, but also still using facelets(not html, like <link rel=...>)? It will be good when the user simply will see the path to the css file as resources/css/styles.css

That's not directly possible without reimplementing the entire ResourceHandler with help of a ResourceHandlerWrapper as answered by lu4242 on this question, which is not exactly a trivial job. It's a hardcoded public static final field constant in ResourceHandler class, the ResourceHandler#RESOURCE_IDENTIFIER. You may want to post a feature request to make this externally configureable like as has happened for the NamingContainer separator character during the JSF 1.2 to JSF 2.0 step.

But why would you do this? There are a lot of other things which gives enough hints about the framework used. In case of JSF that can be the request URL pattern (/faces/*, *.jsf or *.xhtml), the response headers (X-Powered-By), specific hidden form fields (javax.faces.ViewState), the autogenerated client IDs (by default woodstocked), the JS libraries used (jsf.js), etcetera.
