Client (browser) caching
1 Disadvantages of client-side caching
Client-side caching reduces server requests, avoids duplication of files, and significantly improves user locations. But when the site is updated (such as CSS, JS, and picture files), browsers still keep old versions of the files locally, resulting in unpredictable consequences.

First of all, write a simple code example in vs.
The normal attempt to run in VS is no breakpoint debugging, just press F5.
The resulting results are as follows.
When debugging, you need to set at least one breakpoint (click to the left of where you want to set it). debugging starts debugging by causing the program to run to a breakpoint and suspend its operation.
By pressing F5, you can find th

So, to personalize my own VC, start with the shortcut key!
