more_set_headers and manipulating single cookie

@agentzh

I'm trying to solve a problem and this module is very close to intended workaround.

Backend app sets number of cookies and I need to alter value of a cookie in certain circumstances.

When I do:

more_set_headers "Set-Cookie: target-cookie=myvalue";

It does changes target-cookie's value but it removes other "Set-cookie" header from output.

My intention is to change value for target-cookie only without touching other cookies.

May I know is there any workaround for this? Or this can rectified by patching module itself?

Thanks.

Start by reproducing the configuration from the issue with multiple Set-Cookie headers and observe how more_set_headers handles them. Done means changing target-cookie while preserving every other cookie; the issue names no source file or test, so locating the relevant header-processing entry point and adding coverage will require repository research.
