I am amending the title so that it is #1591 only. I think the dependency issue in #1592 is a quicker solve and needs a merge sooner than we will have this one resolved.

See #1595

[harshanarayana]

@ahopkins works for me.

What is the progress on this PR ? And are you targeting this on 19.6 ? @harshanarayana

[harshanarayana]

@yunstanford Yes. I am going to follow the idea discussed in #1591 and split into two work items. Will fix the propagation of strict_slashes flag across. I will update the PR by end of the day.

@huge-success/sanic-core-devs I am good with this change from my end. Please take a look at the changes and see if there is any change required.
