How to record and replay HTTP traffic

The Internet is the number one reason why we are so connected with each other globally. Our ability to reach out to others through social networks, and obtain knowledge is all because of the fast-paced technology and internet connection we have. These interconnections won’t be possible without the software programs and mark-up languages that help us interpret and transmit computer data. 

One of the major reasons we can communicate on the World Wide Web is the Hypertext Transfer Protocol or HTTP. Generally, it was designed to carry html documents and transport them to the client on the web. It gives a solid foundation in data communication in www, which allows us to access internet resources easily.  

Over the years, the protocol was improved, and new features were added, making HTTP the most reliable and quickest data deliverer on the World Wide Web. The HTTP can transfer any sort of data as long as the two communicators can read/understand the context. However, the World Wide Web became a pool of personal information where people often experience hacking problems. Therefore, developers have strengthened the exchange of data by allowing users to monitor the HTTP traffic. 

What is HTTP?

The Hypertext Transfer Protocol (HTTP) is an application protocol used for fetching resources and serving web content. This protocol is the foundation of data exchange in web-based applications. HTTP is known for its client-server protocol, which means there is a request and a response between two systems. The client, which is commonly the Web browser, will initiate a request to the Server. Each request handed over to the server will be interpreted to provide an answer or response to the client.

Understanding the Concept of Analysing HTTP Traffic

Barriers and debugs are inevitable in HTTP. There are instances when the other system in the client-server protocol is not available, and the internet is not the safest place to trust with personal data. Thus, developers poured their efforts into enhancing the security system of the internet. This has pushed the websites to use HTTP, which converts traffic using Transport Layer Security (TLS).

Recording and replaying HTTP traffic will help you gain added information regarding the activities on your network. This can be used to build on the performance and security system of the network you are using and diagnose the production problems. In order to analyze the incoming way of data exchange in HTTP traffic, you have to choose the appropriate application for the system or your network. 

How to Record HTTP Traffic

There are different ways of recording HTTP traffic. One of the most reliable mediums to record the network is Silk Performer Help which records and replays HTTP traffic.

  1. The first thing that must be done in order to start the whole process of recording and replaying traffic is to download all the resources that will be needed. 

These resources depend on which medium can be integrated into your network. For example, in recording the HTTP SOAP using the Traffic Parrot, the requirements needed to download are Java version 8 or above, the UV index application, and of course, the Traffic Parrot.

  1. Next is to extract the resources that you have downloaded. 

In some cases, a recording profile should be created. 

  1. After extracting the file, select the UV Index application or any Application Type Box.

Answer if there is any type of protocol selection area. In some files, you have to ask for a code that will deliver you a link/URL that will lead to the recording settings. 

  1. When you see the “Recording” box in your software, click that button to begin the record of the SOAP responses.

Click the Change GUI Size or Get button to obtain a copy of all the SOAP requests and responses executed over HTTP traffic. 

  1. Then click the “Stop Recording” Red  Button to end the recording.
  2. Script Customization

The SOAP request recorded has a WebHeaderAdd and a WebURLPostBin API call. The parameters of each Web Services can be customized. Meanwhile, the UV Index application in Traffic Parrot does not rely on the third-party EPA API servers. 

How to Replay HTTP Traffic 

Replaying the HTTP Traffic is pretty simple. The recorded file can be replayed using customized scripts. There are different options to choose from in replaying HTTP Traffic. The following are:

  1. Replay the Script in a Test
  2. Start a Try Script Run
  3. Replaying the Start because it is part of the baseline identification
  4. Run the scripts on a different server  

Conclusion

Recording and Replaying HTTP Traffic is a good practice to monitor the data exchanges in our devices. Moreover, this activity can help you identify any imperceptible software problem, which gives you the opportunity to fix them right away.

The process of recording and replaying HTTP Traffic is not that complicated, especially if you studied the concept or if you are knowledgeable with software courses. The recording process requires a server or medium which is easy to identify through research; and testing which file should be downloaded into your PCs and able to perform the recording.
