ASP obtains the client, and how does asp obtain the name of the client s computer?

If you're using aspnet, he has a special function in. NET to get a computer name, IP address and current username is very simple, the following are a few methods I commonly use, if you have other good methods, you can reply and sort it out together:

1.In private properties:

Get the server computer name:

Get user information:

Get the client computer name:

Get the client computer IP:

Your remote host just returns the hostname, which usually refers to the domain name, and sometimes returns the IP because it failed to be verified

You can get it by getting the environment variables.

<%if vip = "" then vip = "remote_addr")

str=right(vip,len(vip)-instrrev(vip,"."))

"Your IP is: <%=VIP%>" You are a user of "<%=str%>"!

Or: <%.

if vip = "" then vip = "remote_addr")

arr=split(vip,".")

"Your IP is: <%=VIP%> "You are a <%=arr(3)%> user!

I'll give you a function.

Obtain the user's real IP, which is still valid for ** address;

function getusertrueip()

dim stripaddr

if "http_x_forwarded_for") or instr("http_x_forwarded_for"),unknown") 0 then

stripaddr = "remote_addr")

elseif instr("http_x_forwarded_for"),0 then

stripaddr = mid("http_x_forwarded_for"),1, instr("http_x_forwarded_for"),1)

elseif instr("http_x_forwarded_for"),0 then

stripaddr = mid("http_x_forwarded_for"),1, instr("http_x_forwarded_for"),1)

elsestripaddr = "http_x_forwarded_for")

end if

getusertrueip = trim(mid(stripaddr, 1, 30))

end function

Just use"remote_addr"This, you get because you run it locally, that's it.

It's the IP address of the machine.。

with"remote_host") to get the hostname of the client.

Used in ASP"remote_addr") to obtain the client's IP address, but if the client is using the ** server to access, then the IP address of the ** server is obtained, not the real client IP address. If you want to get the real IP address of the client through the ** server, you need to use Crack"http_x_forwarded_for") to read. However, it should be noted that not every ** server will work"http_x_forwarded_for") to read the client's real IP, and some of them still read the server's IP this way.

Another thing to note is that if the client is not accessed through the server, use the ("http_x_forwarded_for"The value will be empty. So, if you want to use this method in your program, you can do it like this:

userip = "http_x_forwarded_for")

if userip = then userip ="remote_addr")

That is, if the client passes through the ** server, then take the value of http x forwarded for, and if it does not pass through the ** server, take the value of remote addr.

General function: If you can't get the real IP of the client, you will get the **IP of the client

private function getip()

dim stripaddr

if "http_x_forwarded_for") or instr("http_x_forwarded_for"),unknown") 0 then

stripaddr = "remote_addr")

elseif instr("http_x_forwarded_for"),0 then

stripaddr = mid("http_x_forwarded_for"),1, instr("http_x_forwarded_for"),1)

elseif instr("http_x_forwarded_for"),0 then

stripaddr = mid("http_x_forwarded_for"),1, instr("http_x_forwarded_for"),1)

else stripaddr = "http_x_forwarded_for")

end if

getip = trim(mid(stripaddr, 1, 30))

end function

ASP seems to only have direct functions, but JS does.
