I ran a blogging SaaS platform for a while. I had some instructions for configuring a reverse proxy to serve the blog. There were instructions for most major web servers. One step was adding a custom header.

- Go to <link> and get your publisher ID - Add the following line to your config(replacing xxx-xxxx-xxxxx with your code from the previous step):

AddHeader X-Publisher-Id: xxxx-xxxxx-xxxxx;

We had a bunch of people leave the x's in and were confused why it wasn't working. So we made a blog that explained the misconfiguration, and replaced xxxx-xxxx-xxxxx in the documentations with that blog's ID. We got far fewer support requests after that.
