The useless dhcp quote server option could be reused for this, but that's an IP address, and since most webservers expect hostname and there's a reverse lookup needed, perhaps a new dhcp option is the way to go.

<div><br></div><div>In simple terms, the project is a wireless hotspot for a particular purpose. The hotspot provides content (all legal) and after a product purchase, internet access for a period of time. All that is simple and nothing many people aren't already doing.</div>
<div><br></div><div>The issue that I've recently come up against is HTTPS. Many sites are moving to HTTPS as default. Facebook, Google, etc etc are starting to use it more and more. Now this is not a problem at all, and fully supported as normal web traffic should be.</div>
<div><br></div><div>The problem we're facing is that as per normal hotspot solutions, when a user connects to the hotspot, they get an IP. Then they start a browser, and if it goes to a home-page, it gets redirected to a captive portal page where they click some terms and we move on.</div>
<div><br></div><div>Now that many people are having a HTTPS address as their 'home/startpage/etc', the HTTPS not able to get anywhere and breaking. So to solve this issue, we now also intercept 443 - HTTPD and redirect it back to the portal.</div>
<div><br></div><div>Due to the user trying to go to <a href="https://blah.com/">https://blah.com/</a> being re-directed, the browser is freaking out with an interception or man-in-the-middle attack potential alert and so on. </div>
<div><br></div><div>Now, I think its possible to work our way around this, but the question remains - "Is intercepting HTTPS for redirection purposes - an interception issue" ?</div><div><br></div><div>I am sure there are lots of people who have had this problem and may (or may not) have a way around it... but the question is - is there any legal issues here we have to worry about?</div>
