Starting with this update, pages scraped via this add-on are saved to the internal-data://temp, which is usually located at the root of your forum in the internal_data/temp directory. The filenames will appear as s9e.xxxx.html.gz where xxxx is a string of 32 alphanumeric characters. The files are automatically removed by XenForo after a few days.
In most cases it will not make any difference. In some rare cases, it may slightly speed up embedding links from unreliable sources that require scraping.
