SL notes for today

When uploading files in SL mode, the Server Load balancer 3 does not support TCP and is later upgraded to Server Load balancer 5.

Cross-origin requires that the SL cross-origin policy file clientaccesspolicy. XML can also be the flash cross-origin policy file crossdomain. XML server Load balancer 5, which allows you to enhance trust in the browser.

Basic is successfully uploaded on other machines in the LAN. However, it is feasible to test the maximum file size for multipart upload if some files are not successfully uploaded, in this way, it is meaningful and feasible to display the Real-Time upload progress information when uploading large files.

The progress bar displayed by backgroundworker is OK.

Runworker this method can contain custom states, and then reports the progress on a regular basis to report custom states. It can be used to customize real-time status information and identify roles, you can also report the percentage change event. You can define the UI element to get the custom status and percentage or error information.

The current problem is: 1. The file name to be uploaded is currently obtained through static variables, but it is unstable and not suitable for uploading multiple files. 2. Control the number of requests for uploading files on the client, when too many requests do not respond, the server will return notfound because they are asynchronous requests. Now we have to wait until a certain number of requests are completed before continuing the request.
