cse124_http-socket's Introduction

1 build TCP socket model

steps: create setopt bind listen looping{ accept handleRequest}

ref: https://www.geeksforgeeks.org/socket-programming-cc/

2 handleRequest

2.1        reads multiple requests into a string     like R1/R2/R3...   
2.2       looping to break the requests String and do
    2.21    parsing request 
    2.22    framing response 
    2.23    send header
    2.24    send files         (only if 200 allowed )

3 Testing

3.1     sending single request
    illegal path?   relative path? 
    file permission check
    different file types:    jpg png  html txt 

3,2   multiple  requests in one client message
EX cat  <(printf "GET /testing.txt HTTP/1.1\r\nHost: localhost\r\n\r\n") <(printf "GET /testing2.txt HTTP/1.1\r\nHost: localhost\r\n\r\n") <(printf "GET /testing3.txt HTTP/1.1\r\nHost: localhost\r\n\r\n") <(printf "GET /testing4.txt HTTP/1.1\r\nHost: localhost\r\nConnection: close\r\n\r\n")   | nc localhost 9000

3.3     multi threading to handle multi users requesting and the same time       

3.4     handle timeout. 
        set time out to be 5 seconds for each user, if no request recieved in 5 sec, cut connection.

Project summary, Can do better next time?

1   Overview, 
    find relative resources to understand, find TCP socket programming tamplate
    break projects into steps, 
      
2   Coding 
    apply encapusalation and modularization to design classes and functions 
    focus on programming logic 
        for those new methods to be used, like sys calls, read manual, test individually and then apply in project
    TDD test driven development. Do not test all together, write part and test, then write the following

3   Testing to handle edge cases
    brainstorming to test based on functionalities  
    think deeply
