New features

Preserve query strings when redirecting POSTs to GETs

The GOV.UK Prototype Kit now preserves URL query strings when redirecting POST requests to GET requests.

This means if you have a query like /link/to/something?query=true&hello=world on your POST form action, and you submit the form, the URL query string will be present in the redirected URL.

This feature is useful when you:

• use the query string to set flash messages or return paths
• want to use the values in the query string for a specific page, rather than saved data

Thanks to @edwardhorsford for contributing this issue and its solution.

This was added in #1120: Preserve query string when redirecting POSTs to GETs.

Fixes

• #1155: Replace keypather package with lodash.get
