I've got an AH trends site pretty much done and when I took a break a few weeks ago, I was at the point where I need to obtain all of the data for the items in the AH. I've got pretty close to 10,000 unique IDs from a few week's worth of AH data files and I'm not sure what's acceptable as far as grabbing and caching all of that item data.

Anyone know, or have a link to a post with information like this? Obviously I'm specifically interested in acceptable practices but any other info I might need to know but don't know I need to know would be awesome ;p Yes, I read through the stickies and yes, I searched for several combinations of terms that might deal with my question.
