[pca] Can pca check two different local sources?

Understood, thanks. I could flip the xrefurl elements, and contact the
proxy first.
Or I could leave the config alone, and use a cronjob to check the proxy daily.
I want to preserve a copy of each xref, so that can go into the same script.

I suppose I could miss an updated README, but that's not an everyday issue.
If I'm really concerned, then I'll just delete aging READMEs out of the cache.

Good to know -- I saw the word "proxy", and assumed which you meant.  =-)

Yes that's fine. For me, multi-elements work best if I add scheduled
xref checks.
If networking wasn't an issue, I wouldn't bother with the file:/
element. Thx... -c
