Problems with multiple virtual hosts of apache under windows
Answer
My file directory structure is as follows:
-WebSer
Myroot(1)
-abc
Myroot(2)
Myroot(3)
Now I can access these three independent virtual hosts from Myroot. But there is still a problem. Things in the three directories Myroot(1), Myroot(2), and Myroot(3) are all related. For example, Myroot(1) needs to manage Myroot(2) and Myroot(3). Including writing static files, updating, and uploading. . .
If so, can they still be set up as independent virtual hosts? Will Myroot(1) not be able to manage the other two?
