Mainframe Access normally reads a Web resource (such as an HTML page, GIF image, Java class) from the DASD data sets only once, when the first request for the resource is received from a client. That first request causes the resource to be saved in a virtual storage cache that is used to satisfy all subsequent requests. If you refresh the Web file cache, Mainframe Access responds to subsequent resource requests by re-reading the resource data from the DASD data sets, when the first request for a resource is again received. The refresh function makes it possible for you to update Web resources in the DASD data sets and have the changes take effect immediately.
When you select the Refresh Web File Cache function from the lower-left pane, the refresh is performed immediately. All virtual storage that has previously been allocated by Mainframe Access to cache Web resources is released.
Mainframe Access responds to the refresh request by displaying a page that indicates that the refresh is complete.
