How to open a site of another domain in the same window or frame?

Question

JavaScript

There is a simple page on which the user enters his code, after which the server generates a page on an external domain (there is no access to that domain), if I then try to open this link in a frame - as a result, the page does not load and the console issues X-Frame-Options ' 'SAMEORIGIN' . If I just try to open a link in the same window (location.href or window.open , then for some reason it transfers me to Google.
This problem is only with this site :( if you just open youtube instead, then everything opens fine, everything works the same way if I run my start page just as a file in the browser, i.e. NOT on the server or local host everything works....

Answer 1

Unfortunately, I don’t have access to the site to which the link leads (
Can I somehow open that site with a substitution or without a referral?

Answer 2

It's all about routing. If the domain (computer) exists, but there is no access to it from the Internet, it will be possible to open it only if the domain from which we are trying to open has access to the closed one. If there is such access, you can make something like a staging post. The accessible server requests the page from the closed one, and forwards it to the browser. For the sake of interest, I did this when I was considering options for opening access to the site through the Internet and through a VPN with limited access.
Another question is if there is no access to the domain at all ... If it exists, then only the system administrator can help.

In principle, you can use nginx, and forward the path to an external site through it. Then on your page the path will be considered local, and nginx will redirect it to an external site. But here it is necessary to check how the loading of the page of the external site is arranged. If all the links on it are relative, then everything is ok. If not, then the matter is a little more complicated, but not hopeless.
