; jsp, asp, and php documents are all based on HTML, but use program code to dynamically output HTML code. The characteristic is that the same document can output different values according to different situations. html code.

jsp, asp, and php documents must be compiled to generate html code, which is the result we see in the browser. The difference is that jsp can be compiled by general browsers, asp and

php requires server support, and cgi also requires server support. From a programming perspective, both asp and php can support multi-language programming, including javascript, vbscript or

perl, etc., and even mixed language programming. The document type cannot be determined simply from the extension! You should judge from the server and source code. The ones with <%...%> inside are usually ASP files

, and the ones with $ inside are usually PHP files. Since ASP and PHP generally have limitations, you cannot see the real source code by viewing the source code in a browser or directly downloading the document. You can only see the source code after running it. The generated html, if you really get the source code, you may only be able to attack and crack the server :( aspx is similar to asp, but it only supports .net, which is more convenient in development and more powerful.
