Applies to

acAutoUpgrader and acHTTP components.

Declaration

property UseCache: Boolean; // True by default

Description

The UseCache property specifies whether the AutoUpgrader can use the Internet Explorer cache when it downloading the files required to update application.

Set UseCache property to False if you wish to re-download the file (or part of the file), even if it already exists in the cache, or leave it True if you would like to use cache which will save you the bandwidth and will help to restore broken downloads.

The cache of Internet Explorer is very smart, so it will re-download the files even if they has been updated on the server, even if it already exists in the cache.

Using the cache is recommended! It will save you a lots of bandwidth if connection unexpectedly lost on user PC, or user break the downloading on half way, to upgrade the application a moment later.
