What is an HTTP connection?
An HTTP connection makes possible a digital package to access a web server by using HTTP to transmit files. HTTP or Hypertext Transfer Protocol (HTTP) is an application protocol for transferring files such as text, image, audio, video, and other multimedia files on the world wide web. The main HTTP message types are get, post, and head.
HTTP is the application protocol built on top of TCP. TCP or Transmission Control Protocol on the other side work hand in hand with IP (Internet Protocol) in providing the rules of communication in such a way that interconnected devices understand each other so that they can send information back and forth. TCP makes possible the transport of data across IP networks. This collaborative function makes TCP and IP commonly used together such that TCP/IP has become a standard technical terminology to refer to the basic general protocol of transmitting data.
How does TCP/IP works?
Basically, servers send information. Servers devoted to sending web pages are called web servers. Clients receive information. In this regard, when you search the web using a web browser, your computer becomes a client. Information becomes transmitted over the internet units called packets. TCP and IP are the two protocols (rules for determining the format and transmission of data) required to send these packets.
On more technological terms, TCP is used to split huge amount of packets into smaller ones while the IP handles the routing and addressing of packets.
What is the concept of changing HTTP connections?
An HTTP Connection is a single transaction with an HTTP server using the default HTTP port (80). It is the pipeline of requests and responses of the client and customer. Taking a single TCP connection to address and collect many HTTP replies or requests, as eager to prevent to the opening of a new link for every single request or reply pair, is called the HTTP persistent connection. In this regard, clients can change HTTP connection by changing the “pipeline” for requesting and receiving files.
Meanwhile, clients can also make multiple requests without waiting for a response making possible the single TCP connection to be more efficiently used under a smaller period of time. This is useful for it reduces network congestion by reducing the packets caused by new TCP opens.
HTTP connections limit
There is no limit for changing HTTP connections. However, there is a maximum connections for HTTP in WHM. You can change the maximum value nonetheless in WHM interface by performing the following steps as listed by cPanel documentation FAQ:
STEP 1: Log in to your WHM.
STEP 2: Navigate to the “Service Configuration” section.
STEP 3: Go to “Apache Configuration.”
STEP 4: Click “Global Configuration.”
STEP 5: From here you can already configure the setting by choosing the value for the Max Clients. The value for the Max Clients must be equal to or lower than the value of the Server Limit setting.
