Support disabling of browser proxy pass-through

[kapishmalik]

resolves => #1909

Added flag in global settings to control proxy pass-through. By default, it will be true and allows the request to go to the original URL. If flag will be false, it will return nearest matching stubbed request.

@tomakehurst you can review this PR.

Looking good so far. Please can you add an acceptance test that demonstrates this?

BrowserProxyAcceptanceTest is probably the right place for this.

[kapishmalik]

@tomakehurst I have added acceptance tests.

Again, looking great.

One thing I meant to mention (apologies for not remembering before) - please can you also add a flag to Options for this, so that it's also possible to set it via the CLI and on programmatic startup?

The value from this can be used to set the default in the global settings I think.

@tomakehurst yea yea sure, no worries. I will do the same and get back.

[kapishmalik]

@tomakehurst I have added flag proxy pass through as option via the CLI and on programmatic startup.

@tomakehurst I have incorporated all comments. Could you please check this PR.

[kapishmalik]

@tomakehurst I have incorporated review comment changes. You can review and let me know.

OK, I think this looks good so I'll merge it assuming the build is OK.

One last request - please could you open a PR against the docs repo to add the relevant documentation for this?
I think the standalone (for the CLI bits) and the proxying pages are the ones to aim for.

[kapishmalik]

Sure @tomakehurst I ll add another PR for adding relevant documentation.
