How to make my URL mapping case insensitive?

Question

Grails, by default, is case-sensitive when mapping URL to controller actions or views.

For instance, www.mywebsite.com/book/list will work BUT www.mywebsite.com/Book/list will return a 404 page.

What can I do (code snippets are welcomed) to make my URL case-insensitive (i.e. www.mywebsite.com/Book/list being a valid url) ?

Answer 1

Just a shoot from the hip, try the following:

static mappings = {
"/$controller/$action?/$id?"{
    controller = controller.toLowerCase()
    action = action.toLowerCase()
}

Answer 2
