Adding to this thread just so's I will remember where I parked the information. I recently had occasion to ask a group of random people to look at a couple of pdf files, about 500k and 1.1mb respectively.
Holy ###. I thought my logs were going to explode. A handful of visits picked up each file in a single 200 fetch. But most took 10, 20 ... I think the record is 50 requests between the two files.
The one-page-at-a-time explanation (above) makes it all understandable. Interestingly, the worst offenders were Firefox. Conversely, the all-at-a-gulp requests included back-to-back MSIE 8 and iPad. Go figure. And the timing between requests corresponds well with humans riffling through pages looking for a particular target.
I wondered briefly why I never saw the same behavior in a clutch of large ebooks I offer as PDFs ... until I remembered that they are only available as downloadable zip files. No chance for the reader to stop midway.
