query string parameters are reordered

[wydengyre]

For example, a GET to a URL that terminates in ?b=1&a=2 will actually get sent as ?a=2&b=1. This is surprising behavior, and can lead to very subtle bugs.

This has caused issues in our systems. We did not expect the query parameter to be reordred when an explicit string including query paramters were given as the target url.

A fix or setting to avoid this behaviour would be greatly appreciated.
