This file contains a suite of HTTP client server programs. The clients, chopper.c and ahsoka.c send TCP GET requests to the server, starLord.c. The server accepts and parses these incoming requests to make sure that they are valid requests. After it has parsed the requests, it identifies whether it should perform an add or view on the data that it has parsed. If it adds, it prepends the host header to the message it received, appends a newline, and then places all of that into a local buffer and sends the contents of the buffer as a payload in an http response. The chopper.c client can be run two ways, the first way accepts a string as a parameter at the command line and sends it in the payload of an HTTP GET request, and then waits for a response from the server and displays it. The second way allows it to make another, seperate GET request. The ahsoka.c client follows a similar process, but verifies that the server actually does its job correctly. It does this by sending a series of add and view requests, and then comparing the returned buffer with the expected output The flags given below MUST be used at runtime in order for the applications to run properly, although the order that they are supplied in is entirely up to the user. i.e. specifying the message, then the port, then the server will not affect the program, provided that each of those are present along with their corresponding flags.

In order to compile these programs, a makefile has been provided that will run with the command "make." After they have been compiled, each executable can be run according to the syntax given below. They can be run on a single or multiple devices, but each program will need to be run in its own command line shell.

| | | starLord.c | |______________________________| accepts input in the form of: starLord -p

where: -p: serverPort: The 16 bit port number the server should use. You should generally run the server with a port number in the 5K to 10K range.

and will then output:

chopper -s -p -h [-a ] [-v]

where: -s,-p,-h,-a, and -v are flags corresponding to -s: serverIP: is the IP address (in dotted name format) of the host that is running the server side. -p: serverPort: is the 16 bit port number the server is using. You should generally run the server with a port number in the 5K to 10K range. -h: hostHeader: is a string parameter and if it includes whitepaces, should have the appropriate quotation marks. -a: message: is a string parameter and if it includes whitepaces, should have the appropriate quotation marks. -v: if this flag is included, client will create a view request and the content of the message will not be sent as an add request

and will then output:
