Differences between include file and include virtual

1. # Include file: The relative path of the file to be included; # include virtual path of the file to be included.
2. In the same virtual directory, <! -- # Include file = "file. asp" --> and <! -- # Include virtual = "file. asp" --> the effect is the same, but if the virtual directory is named myweb, <! -- # Include virtual = "myweb/file. asp" --> debugging is also supported, but we know that <! -- # Include file = "myweb/file. asp" --> An error is returned.
3. If a website has two virtual directories: myweb1 and myweb2, myweb1 has a file file1.asp, and myweb2 has a file file2.asp. If file1.asp wants to call file2.asp, write it like this in file1.asp: <! -- # Include virtual = "myweb2/file2.asp" --> in this case, # include file cannot be used. <! -- # Include file = "myweb2/file2.asp" --> An error is inevitable. On the contrary, files in myweb2 that contain myweb1 are the same. If the contained file is under a folder, you only need to add the folder to the virtual path.
4. Whether using # include file or # include virtual, using "/" or "\" in the path does not affect the compilation effect, ProgramIt will be executed smoothly.
5. The preceding situation does not apply to the mutual calling of two site files, and is in the same site. <! -- # Include file = "file. asp" --> and <! -- # Include virtual = "file. asp" --> equivalent, but assume the site name is website, use <! -- # Include virtual = "website/file. asp" --> is incorrect.
