5.4 Changing the Web Pages Rendered by Web Server

As indicated in the previous section folder, /fs (file system that is rendered) contains the present html files and java scripts that are being rendered by the active web server. The contents of the folder can be converted to an .h file containing various data structures as in io_fsdata.h using the utility in tools/makefsfile.exe as shown below. (There is also a perl script available at location third_party\lwip-1.4.1\apps\httpserver_raw\makefsdata. You can read through the script to get a better understanding of the utility).

makefsfile.exe -i fs -o io_fsdata.h -r -h -q, where:

  • fs is the folder containing the file system (html files, java scripts, images, and so forth) that is being rendered by the web server.
  • io_fsdata.h is the .h file generated.
