Click on the "PreloadNetThing" button to preload the HTTP item specified in the field at right into the browser's disk cache.
PreloadNetThing can also be used to determine the MIME type and date last modified of an HTTP item.
When using PreloadNetThing you should be aware of the following:
1. You can never be sure when a preloaded item has been cleared from the disk cache.
2. In most cases, attempting to preload a file that does not exist will not generate an error, as the HTTP server will return a text file telling you that the file you requested does not exist.
