JSP
Like PHP, JSP is also a good choice. JSP is one of the important Java contributions of Sun, or it can run on Apache or Sun's Java Web Server. Another ASP2JSP can automatically convert the ASP page into a JSP page.
Perl
The old PERL language is also very popular in the past. The founder LARRY WALL has been described as a lazy person, thus created this simple programming to save the time of writing programs. Perl can run in all web servers (regardless of IIS or Apache) or on the operating system (including Mac, Windows, Unix, Linux ...).
Oracle 9ias Migration Kit for ASP
Oracle's important products can convert ASP applications to JSP, while Oracle also provides a good database conversion tool. Of course, Oracle products are not cheap.
What is the problem with the conversion?
To be converted to Linux by IIS, it is of course inevitable to encounter some problems. For example, a static web page is replicated with a diagram file. The problem encountered in this part of the problem is usually less, can be manually replicated slowly, as long as spending more time patience, of course, the LSP is automatically replicated.
Apache has full support in terms of directory permissions and virtual directory settings. Of course, as Samba, you must have some basic understanding of Apache's setup file syntax, or you can use Webmin and LSP assistance settings, and LSP automatically converts IIS's settings to Apache.
