HTML Report Cache [Pro Edition Only]
TrafficReport includes a neat time-saving feature called a Report Cache. The cache makes it possible to run daily month-to-date or year-to-date reports in the time TR takes to run a report on a single-day log. By activating the cache, TR will remember the report information it creates from your Logs. In subsequent reports, TR just needs to read the portion of your Logs that were added since its last report.

By default the cache is off. To turn it on, check the Report Cache group box. TR names the cache file TR Report Cache 1. You can change the name in the Cache File Name edit field. The Place File In group shows you which folder TR will place the cache file. By default, TR uses the folder that contains itself. To choose a different folder, click the Select... button.
Another important thing to keep in mind is that all settings that limit which log entries TR includes in its reports, including Filter, Scope and Domain settings, affect which entries are stored in the cache. If you change these settings, they dont retroactively affect entries already in the cache. If youd like these settings to affect the entire report (rather than just new entries added to the cache) delete your cache file. If you enable reports that had been disabled, such as the Visitors report, you should delete the cache file. This is important since the newly enabled reports and information will not have been produced (to conserve memory) for previously read portions of your logs. Likewise, if you change the Agent, Object, OSor Referrer categories (by adding, deleting or modifying a category) you should also delete the cache file.
