Have WordPress (or Apache) read a link in a file and use it as a link on a page?
The subject describes the matter, I think. Using an API, I'm provided a link that changes often, that I need to serve in my WordPress blog. I can easily cron a wget to get me the file. The question is how I use the link contained in that file as a link that will autoupdate in WordPress?
If you don't know how to do it in WordPress, but you do in Apache, that might get me closer.
