Psychz networks guide focuses on the identification and resolution of HTTP errors most commonly encountered (error 403, 404, 500.503) and that from the viewpoint of a system administrator. There are many situations that can lead a web server to respond to a request by a particular error code, we will cover the causes and the most common solutions.
When you are going to access a dedicated Web server, each HTTP request received in return will receive one HTTP code. These kinds of HTTP codes are classified into five categories. The category of a code could be understood by looking at the first digit:
1: This is the code for Information
2: This is the code for Success
3: This is the code for Redirection
4: This is the code for Client Error
5: This is the code for Server Error
The errors or the codes ranging between 400 and 499 can be considered as the outcome of HTTP request from a client. While these types of errors are related to customers, it is often useful to identify the code to see if the problem can be solved by modifying the configuration of the server. The server error or the codes between 500 and 599, are the ones returned by the server as it understands that there is an error committed when process any request. The HTTP 403 code, or error Forbidden, means that the user has made a valid request, but the server is refusing to service the request because of a lack of rights to use the requested resource. According to psychz networks, if you get an error 403 on the dedicated server, here is a list of possible causes:
File not found index
Here is the most common cause for error of 403. When you connect to a site, the default Web server will open the page named index (html or php). If this page does not exist the server may return a 403 error. In this case you can either recreate an index page or configure web server vote that opens another page default.
Permissions to any files
They usually happen when the user performing the HTTP request does not get any permissions to check any requested file.
