How to prevent direct access to *.gsp pages in Grails

Could anyone advise a feasible solution to prevent direct access to *.gsp pages on Grails?

After reviewing intercepting '/**.gsp', I found it is impossible to use that as it not only filters out direct access, but also the pages rendering from controllers, etc.

I tried to setup the following in UrlMapping.groovy, even though I can prevent the *.gsp direct access, but I also make a mess to the navigation of the pages; all the links seem to go to home page then.

    "/**.gsp" {
isEligible = {
    System.err.println("ALL PARAMS: " + params)
   request.requestURL.toString().endsWith(".gsp")
}
controller = {
    if (request.requestURL.toString().endsWith(".gsp")) {
        "public"
    } else {
        "*"
    }
}
action = {
    if (request.requestURL.toString().endsWith(".gsp")) {
        "home"
    } else {
        "*"
    }
}
}

Once I thought about setup filter like org.springframework.web.filter.OncePerRequestFilter, but not quite sure how to define it probably as Grails tends to generate the web.xml filters section by itself.

Any thoughts?

Thanks a lot! tom

Add these to UrlMappings:

"/**.gsp" {
    controller = {
        if(request.requestURL.toString().endsWith(".gsp")) {
            "forbidden"
        } else params.controller
    }
}

And create a ForbiddenController and an index.gsp with "Never think of accessing GSPs directly dude." as its content.

Cheers.

What about writing a filter that will be executed on each request ?

unfortunately I did not find a solution with UrlMappings. here is a solution which is little bit ugly but if you use the same layout (for example main.gsp) on all pages you could add this lines to the layout (main.gsp).

    <%  if (request.requestURL.toString().endsWith(".gsp")) {
       response.sendRedirect("${request.contextPath}/")
    } %>

this way if the user tries to access the gsp page direct he gets redirected to the home page.

maybe not the best solution but did work for me so far.

according to the grails FAQ the "/**.gsp" configuration in the UrlMapping.groovy should work.

couldn't try it out yet.

How did you add the links to the page ? Are the links also broken when you use the link tag ?

<g:link controller="book" action="list">Book List</g:link>
