Wired article Error codes and response codes are used in various programming languages to describe a variety of events in the internet world.
A simple HTTP error code (code 300) is an indication that a request was not processed correctly.
HTTP response codes (e.g., 404) are used to indicate a response error or a network error occurred.
In this tutorial, we will take a look at how HTTP error codes and responses can be used to test web applications.
To test the application, we need to specify the requested page and we need an HTTP response code that can be read as either 300 or 404.
If you don’t know the value of a HTTP responsecode, check out the free sample application that can test it for you.
Let’s go ahead and get started.
HTTP Error Code Example 1: Error Code 300 This is a typical HTTP error Code and Response Code.
300 means that the request was successful.
301 means that an error occurred during the request.
302 means that there was an error in the response.
3 means that you are not allowed to continue.
4 means that no response was received.
5 means that we have an error.
This response code is typically used by web applications to indicate errors or network problems in the network.
HTTP Response Code Example 2: Error code 400 This is the same response code as the 301 response code.
400 means that a connection was lost or that an HTTP error occurred while processing the request or while trying to read from the network, respectively.
401 means that HTTP response data is not valid.
402 means that this request was unsuccessful.
403 means that some error occurred with the request, but we have no way to get a clear understanding of the problem.
404 means that none of the above is true.
This status code indicates that the server is down or the network is unavailable, and it indicates that no data was received from the server.
HTTP Code Example 3: Error codes 403, 404 This response status code means that certain data was not received from a connection or network.
404 indicates that some data was sent, but the data cannot be verified because it is invalid.
400 indicates that a network connection failed.
401 indicates that an invalid network request was received, but there is no information on the server to determine what happened to the connection.
402 indicates that data was written to the network without authorization, but no data could be read from that data because of network limitations.
404 is a more common status code and indicates that HTTP status code 404 is an invalid response.
It means that data sent from the web server to a web application has been invalidated.
HTTP Responses Code Example 4: Error 404 The 404 response code indicates the server received an invalid request, or a server error, and that the requested data cannot have been received.
400 is a much less common status and indicates the application was unable to retrieve the data.
The server response code 404 indicates an error on the part of the web application.
HTTP responses can also indicate that the data has not been received or is incorrect.
HTTP Codes are used as a way to describe data that is not currently available in a database, such as a list of contacts or emails.
You can use HTTP codes to determine the content of an incoming HTTP request or HTTP response to indicate that data that was not properly requested is no longer available on the web.
The following HTTP codes are commonly used to represent HTTP responses: 200 HTTP/1.1 200 OK Content-Type: text/html 201 HTTP/2.0 201 OK Content/Type: application/json 202 HTTP/3.0 202 OK Content /Type: object 202 HTTP.1 302 Content-Length: 1023 302 Content/X-Requested-With: Content-type/application/json Content-Disposition: text content-length-type Content-Version: 1.0 X-Originating-Origin: https://example.com/ 302 HTTP/4.0 302 Content Content-Transfer-Encoding: gzip/gzip-1 Content-X-Origination-Origin-Date: Tue, 09 Mar 2013 09:23:12 GMT X-Content-Type-Options: nosniff X-Request-Id: 3fc2f6a1-d2f5-45a2-abd8-c4d2a7f9d5ca X-Disabled-X: true X-Cache-Control: max-age=31536000 Content-Security-Policy: maxage=30 Content-Policy-Target: application-id X-Priority: 1 Content-Accept: text; charset=utf-8 Content-Encodes: gzipped; charsets=utf_8 X-Last-Modified: Thu, 01 Mar 2013 18:47:46 GMT X
