Nsk Scraper
Spider read nsk.su in 2.0 s without a browser and returned 707 lines of clean markdown, including sections like "Why Use Shell Scripts for CGI Support?" and "Security and Data Concurrency Issues".
* When to use other tools for CGI-BIN (like C/C++ and Perl)* How to deal with security and data concurrency issues* How to get started with CGI-BIN scripts* How to send responses back to the user with dynamic HTML* How to retrieve data with CGI-BIN scripts## **Why Use Shell Scripts for CGI Support?**CGI can be written using a number of tools including shell scripts in Korn andC shell, Perl, and even compiled languages such as C or C++. There are a number ofreasons to pick or avoid a particular tool. Many people frown on coding CGI scriptsin shell scripting languages because of the limited programming capability thoselanguages provide. In addition, shell scripts put a larger load on the server systembecause they are interpreted and must invoke other processes to perform many functions(to translate they execute the UNIX tr command for example).The biggest disadvantage of using a shell script with CGI is that security problemsoccur very easily. CGI scripts run as though you signed onto the server and executedthe script interactively. In fact, one of the best debugging methods is to run yourCGI script while signed on the server interactively. If the script is not writtento properly prevent unintended access, an outsider is executing commands from insideThere are significant advantages to coding your CGI in shell scripts. First ofall, they are quick to develop and relatively easy to debug. Secondly, shell scriptstend to be portable to any server that is running UNIX. Most UNIX platforms supportversions of the Korn and C shells. The third reason is that most UNIX technical professionalsalready know how to code shell scripts. The final reason may be forced on you--theInternet Service Provider (ISP) or administrator of your server may require it.### **Security and Data Concurrency Issues**You must code your scripts carefully to prevent input data from being executed.The same call, in code.
