cooked requests
A request is an HTTP command that a browser sends to a web server. It can be a GET request, which is what your browser does when you type a URL into the address bar and hit enter, or a POST request, which is what happens when you submit a form.
If you’re making a request to a server that you don’t control, chances are good that the server is going to give you back a response in the form of an HTML document. If you’re making a request to a server that you do control, the server can give you back anything it wants – an HTML document, an XML document, a JSON object, an image, a PDF… whatever.
When you make a request to a server, the server will process your request and then send you back a response. The server will decide what kind of response to send you based on the request that you made.
If you’re making a GET request, the server will typically give you back an HTML document. If you’re making a POST request, the server might give you an HTML document, or it might give you a JSON object, or it might give you an XML document – it all depends on what you’re asking for.
In order to make a request, your browser needs to know the address of the server that you want to make the request to. This address is called a URL, and it stands for Uniform Resource Locator.
A URL is made up of a few different parts:
The protocol – this is typically http or https
The hostname – this is the domain name of the server, without the www
The path – this is the specific location on the server that you want to make the request to
The query string – this is any additional information that you want to include in the request
In order to make a request, your browser sends a message to the server at the URL that you specify. This message is called an HTTP request.
The server then processes the request and sends back a response. The response is also in the form of an HTTP message.
The first line of the HTTP message is called the status line. The status line contains a status code and a status message.
The status code is a 3-digit number that gives you information about the response. The status message is a short phrase that describes the status code.
Here are some common status codes:
200 – OK
The request was successful and the server was able to find the resource that you were looking for.
301 – Moved Permanently
The resource that you were looking for has been moved to a new URL.
302 – Found
The resource that you were looking for has been moved temporarily to a new URL.
400 – Bad Request
The request that you made was invalid.
401 – Unauthorized
You are not authorized to access the resource that you were trying to reach.
403 – Forbidden
You are not allowed to access the resource that you were trying to reach.
404 – Not Found
The server was not able to find the resource that you were trying to reach.
500 – Internal Server Error
An error occurred on the server and the request could not be completed.
Each HTTP message can also contain a body. The body of the message is the part of the message that contains the actual data.
The body of the message is optional, and it’s up to the server to decide whether or not to include a body in the response.
If the body of the message is encoded in JSON, it will look something like this:
{ “key1”: “value1”, “key2”: “value2” }
If the body of the message is encoded in XML, it will look something like this:
value1value2
The body of the message can be encoded in any number of ways, but JSON and XML are the most common.
When you make a request to a server, you can specify what kind of data you want the server to send back to you. This is done by setting the Accept header of the request.
The Accept header is a list of all the types of data that you are willing to accept. The server will then choose the best type of data to send you based on the types that you have specified in the Accept header.
If you don’t specify an Accept header, the server will assume that you are willing to accept any type of data.
Here is an example of an Accept header:
Accept: application/json, text/xml
This header specifies that the browser is willing to accept JSON and XML data.
When you make a request, the server will send you back a response. The response will contain a header called Content-Type that specifies the type of data that is in the body of the message.
If the body of the message is encoded in JSON, the Content-Type header will look something like this:
Content-Type: application/json
If the body of the message is encoded in XML, the Content-Type header will look something like this:
Content-Type: text/xml
The Content-Type header is important because it tells the browser how to decode the data in the body of the message.
If you make a request to a server and the server sends you back a response with a body that is encoded in JSON, but you don’t have a Content-Type header that specifies that the body is JSON, the browser won’t know how to decode the data.

rootkits
A rootkit is a malicious software program that is used to gain administrator-level access to a computer system without being detected. A rootkit can be used to install other malicious software on the system, such as viruses or Trojans, or to simply allow someone else to remotely control the system without the user’s knowledge. Rootkits are typically installed by exploiting vulnerabilities in the operating system or other software, or by physically accessing the system and installing the rootkit manually.
Most rootkits are designed to hide themselves from view, making them difficult to detect and remove once installed. Many rootkits can hook themselves into the operating system’s kernel, giving them full control over the system and making it very difficult to remove them without causing damage to the system. Some rootkits can even survive a system reboot, making them even more difficult to get rid of.
If you think your system may be infected with a rootkit, it’s important to run a reputable anti-malware program to scan for and remove the infection. It’s also important to keep your operating system and software up to date, as this can help prevent rootkits and other malware from being installed in the first place.
