programming tips for TCP/IP stacks in webservers
The key to the implementation of a mini-webserver is the programming of the TCP/IP stack. Although this is strictly defined, there is nonetheless a certain amount of variety in actual versions of the TCP/IP stack. This article provides recommendations and advice relating to the programming of TCP/IP stacks.Which software modules must be present in a webserver? The client is a general user of the Internet or intranet, and it logs on to the network using standardised software (tonline, AOL etc.). After the usual logon procedure, we find ourselves on the homepage of the provider, which is displayed by the browser. The first connection link has thus been built up that far, and it remains active. From here, we could select our embedded webserver as the next step. After it has been selected, the webserver sends its standard page via the network to the client station. The selection process includes a test of the client ID as a minimal security barrier.
