Config.groovy in Grails: grails.views.default.codec - why base64?

Question

The Config.groovy setting "grails.views.default.codec" specifies the default codec used to encode data with ${...}.

This config setting can take any of the values "none", "html" and "base64".

I understand the reason to why one would set them to "none" (no filtering required) or "html" (to avoid XSS-attacks), but why would anyone like to set it to base64-encoding?

Please provide a specific use-case when it would be appropriate to set it to "base64".

Answer 1

There is most probably no real use case for this. It should just illustrate that you can use any codec (bundled or your own) as the default codec for views.
