Hey Guys! Here I talks about the importance of error codes that may show up in your browser window when you browse a web page on it. When an issue happens loading a website page, an error code and message will show up in the browser rather than the webpage. The mistake code and message that shows up is controlled by the type of error. Commonly the error code comprises of a 3 to 4 digit number and a short message describing the error. Here, you will discover a list of the basic http responce codes and a few steps for resolving them.
