Authenticate via HTTP protocol

I have idea to make authenticate via HTTP protocol

for example

I define following URL to recieve id and password via query string

http://localhost:8080/auth.jsp?id=name&pwd=password

Client (Window application maybe Java or other language) call this url to authentication.

After recieve request from client, Server will do some step to authen (check with database or whatever)

and send response back to client. Client use result response to determine authenticate is pass or not.

I test with this concept with JSP/Serlvet and Java app, Seem it work

but I concern with some reason following

1. Performance issue becuase authenticate take by HTTP on port 8080

2. Concurrent

3. This is weird authenticate process?

Please suggest me

Thank you
