This seems specific enough that's it's probably a me problem, but thought I'd check.

Starting a few days ago when I click on a link in cougarboard on my iPad using Safari, I get a blank white page that says:

Bad Request
Your browser sent a request that this server could not understand.
Size of a request header field exceeds server limit.

I did update my OS to iPados 17.4.1 last week, so that may be related - although the error started happening several days after that. It started out happening occasionally, now it happens every time I click on a link.

Cougarboard seems to be the only site affected... I'm not getting it with other sites. It works fine when using Safari on my iPhone. It also works fine when using Chrome and Brave on my iPad. It's only when I use Safari on my iPad.

When I get that error, if I close out Safari and reopen it, then the link I tried to access does open up. But clicking on any other link goes back to the "Bad Request" message.
