https:// links don't always work

Hi there, I’m trying to pull in relevant web pages from other https:// sites and the results are not consistent. Examples: from the editor screen I go to Add, More, Embed a Site, and paste the following address: About Gliding - British Gliding Association
…which works perfectly well. But this: https://www.dundee.ac.uk/people/andrew-black/
…does not work. It gives an error saying the dundee server is blocked, refused to connect, and it gives the error code ERR_BLOCKED_BY_RESPONSE.
What is the difference between these? Why does one work and not the other?

It’s because UoD don’t want you embedding their site on yours and have configured X-Frame-Options to deny other domains from doing so.

There are ways around this. You can proxy their page through a server you control and re-serve it without the header. This is probably a bit naughty.

OK, thanks Lee. I’m on good terms with them, and they’ll probably help once they know what the problem is.
