Research Http error code
16小时前
It's so shamed to say that during the previous years of development, I experienced several Web projects, but some basic content have been overlooked. Taking Http protocol internal error as example, I never understand it deeply, only go through Google to check solution while encountering the project application . So currently I need to review and start study again. Details are as following in CHS: 2xx 成功
