You might want to make this a different URL than request_url, since it's the URL
the captive portal is redirecting the user to.

In fact, how about making it a request param as in
CreateSafeBrowsingBlockingPage? So a url like

chrome://interstitials/?url=https://google.com&landing_page=https://captive.portal/login&wifi_name=CoffeeShopWifi

would display a warning for https://google.com URL, https://captive.portal
landing page and CoffeeShopWifi wifi name.

I think using request params is a good idea. Thanks.
It gives much clear description of page.

I will use google.com for request url. For landing page, Can I use an external
url like https://captive.portal.com? Or shall I use
https://captiveportal.example.com instead because example.com is not owned by
anyone.

[meacer, 2015/06/19 18:48:59]

Either one works since we aren't issuing any requests. https://captive.portal
looked cleaner to me :)

[meacer, 2015/06/19 17:46:25]

Space between landing_url and nullptr.

Doing |git cl format| before uploading the code saves some time :)

Thanks. I forgot the command. It really save time.
