[Solved] Auto redirect http -> https


#1

Glitch apps respond to both http and https protocols.

Is there a setting or something to force https?

I adapted a StackOverflow answer into some Node/Express middleware:

function ensureSecure(req, res, next) {

    if (req.headers["x-forwarded-proto"].match(/https/g)) {
        return next();
    }

    res.redirect(302, `https://${req.hostname}${req.url}`);
}

I initially had the thought to use the ‘global’ regex because Glitch’s “x-forwarded-proto” header repeats the protocol 5 times :smiley:

'x-forwarded-proto': 'https,http,http,http,http'

But then I noticed that regardless of whether I connect via http or https, the request gets the same “x-forwarded-proto” header value! So my conditional is useless.

I don’t know enough to phrase this correctly, but I’m guessing the forced https setting will have to be set in .htaccess or config file somewhere.

There’s no setting, we leave it to project authors to implement. We used to force http to https, but that was problematic for some use-cases. The following project example works: https://glitch.com/edit/#!/large-patch it’s very similar to your approach, but correctly identities http requests.

Thanks @Gareth,

After reviewing your linked project, and re-reviewing my proposed middleware above, I realized that I was not looking closely at the request headers I was logging.

I incorrectly stated that the headers were the same regardless of access via http or https:

'x-forwarded-proto': 'https,http,http,http,http'

In reality, if I connect using plain http that header is:

'x-forwarded-proto': 'http,http,http,http,http'

The headers are different; I just missed the difference. Your demo using indexOf achieves the same goal as my regex, which got me wondering why yours worked and mine didn’t. Which got me to take another look at the headers as I logged them.
