@bendodd made a great initial implementation of this at, specifically at . I rerolled it at , with the following feedback:
Not yet committed. Rerolled version attached. There were several formatting issues in the help, you had renamed "File Conveyor mode" to "Origin Pull mode" in the UI, but had not reflected this in the help. This is also incorrect, since File Conveyor mode can also be used for Origin Pull mode. The section you were referring to in cdn_help_index_page() no longer existed. I've fixed all these problems, except for one: the lack of variable expansion in advanced_help. Hence you see "!extensions" at the Far Future Expiration help page. This is not acceptable. Surely, there must be supported somehow. Please create a new issue for this.
I'll post a rerolled version of that patch here ASAP.
