i didn't know about httpsoft, thanks for the pull request.

is this implementation linked to yii or not really? if it has some default ties, you could define a "stickyness" rule to pick httpsoft when yii is present.
if you add it there, also add a test case to the installation check

the roave BC check step is broken, we unfortunately need to ignore it for now.

can you please rebase on the 1.x branch?

No. httpsoft is independent organization.

can you please rebase on the 1.x branch?

Done.

[dbu]

thanks!

@nicolas-grekas any concerns or ok to merge?

btw, i noticed that you use the psr-7 integration tests. if you want you could add httpsoft to the that repository to increase visibility of httpsoft.
