The URL is invalid: two slashes are needed after the http(s):. #417

Hello,

I have managed to get cors-anywhere setup on my plesk server :) But I seem to be running into an issue I cannot figure out, no matter what URL I use I am presented with the error: " The URL is invalid: two slashes are needed after the http(s):. "

This error shows no matter what URL I try to access for example:

https://mycorsproxy.url/http://google.com https://mycorsproxy.url/https://google.com

Am I missing something obvious here? Any help is much appreciated, thank you!

Same issue! I´m using Azure Cloud

You have something else running in front of CORS Anywhere that normalizes the URLs. You should disable that URL rewriting mechanism, to preserve the original request URL. If that is not possible at all, an alternative is to omit the scheme.

From a quick search, it seems that Plesk uses Apache. See https://github.com/Rob--W/cors-anywhere/issues/308

For Azure Cloud, see #82.

Thank you for pointing me in the right direction, turning off nginx proxy mode under nginx settings solves the issue in Plesk.

Cloudflare Workers W3C URL JS class has a well known bug that turns "//" into "/" . The CF bug can be googled.

If this is useful for someone

Here is a config for nginx

  1. start your cors-anywhere at localhost:4200
  2. Add this config to the nginx
  merge_slashes off;
  location / {
      proxy_pass          http://localhost:4200/;
  }

On PaaS platforms (e.g. Heroku) where there is no "nginx" to configure, add a check before https://github.com/Rob--W/cors-anywhere/blob/70aaa22b3f9ad30c8566024bf25484fd1ed9bda9/lib/cors-anywhere.js#L312 (some may choose to fix the parseURL function instead)
