Collect more real-world examples of sites that exceed header length limit to inform documentation

I ran into this in Docksal (local development) with Apache 2.4. I went around and around before realizing it was the Surrogate-Key in the header. I am also using Paragraphs and with all the nesting, there are many entries in there.

In my case, only pages with lots of Paragraphs were failing.

In our case, we are using Search API and have a facet for a taxonomy that has hundreds of entries. Because the facet becomes invalidated by changing any of the terms within that taxonomy, the search results page has cache tags for basically every term on the site.

I suspect maybe this has something to do with solr, though there is no search and no blocks on this node page. It works ok, and the page loads listing these keys when logged in as a user other than the owner of the node:

When the author of the node accesses the page they actually get a 502 error.

We have a search api index view of commerce product variations with facets. Each user has their own prices (pulled from an API), plus a default price for anonymous users. We received a report that invalid prices were being displayed (prices from other users). Obviously very bad.

I see a bunch of these warnings, most reference the faceted URLs (/products/{product-type}?f%5B0%5D=configuration%3A1088.

I tried rebuilding cache, but I just keep seeing the same message.

What can I do to resolve this?
