How to follow redirects prompted by DDoS Guards about faraday_middleware

[iMacTia]

Hi @doutatsu, I believe the confusion here is that FollowRedirects only follows "hard" redirects. That's when the server returns one of the 3xx status codes together with a Location header indicating the redirect location (see https://github.com/lostisland/faraday_middleware/blob/main/lib/faraday_middleware/response/follow_redirects.rb#L7).

To my knowledge, those pages you're referring to work differently. The response in that case is a 200 status containing an HTML body (hence why you can see the page on the browser), which normally redirect you to the right page after a few seconds. This uses either a meta tag or a JS snippet to accomplish the redirect.

I'm afraid in such case you'd need to parse the response body (HTML/JS) and look for the redirection url, and this is something outside of the scope of the FollowRedirects middleware.
There might be another middleware accomplishing what you need (though I've never encountered it), or you might write your own middleware and reuse some existing gem that does the heavy lifting in the implementation.

Please let me know if the above helps and if you have any further question!

Thanks for a detailed response @iMacTia - I was suspecting this, but wanted to double-check. I'll need to see if there is anything in the response with the URL, but I suspect they redirect using JS, which won't work with the plain HTTP request

Glad that was at least helpful and sorry for not being able to provide an actual solution. I'll close the issue for now but please, should you find a way forward, could you kindly share it here as well? I'm sure other people in future may find it useful 💪.

I'm obviously available to answer any further question as well, especially if you decide to go down the road of writing a middleware 🙌!
