What does "Proxy-Connection: close" mean in the Ethereal data

Hi everyone,

I have a question about what the "Proxy-Connection: close" in the Ethereal data mean.

Now I have a following problem.

Three web servers are connected to the CSS and load balanced by CSS.

And I confirmed the following;

Case 1:

Client accessed the server with HTTP via CSS VIP address, web page can NOT be displayed completely because client can not get ".gif" file from the server

Case 2:

Same Client accessed the each three server with HTTP via each server's real IP address, web page can be displayed completely.

In the Ethereal data, I found the differentiation between Case 1: and 2: above.

Case 1:

- Client send HTTP GET request to CSS VIP

- CSS send back to Client with "Proxy-Connection: close"

Etherreal Frame: From Client to CSS VIP

Hypertext Transfer Protocol

GET http://www.xxxxxxxx.co.jp/img/yyyy.gif HTTP/1.0

Request Method: GET

.

Proxy-Connection: Keep-Alive

.

Etherreal Frame: From CSS VIP to Client

Hypertext Transfer Protocol

HTTP/1.1 200 OK

Response Code: 200

Proxy-Connection: close <<<---- here

.

Case 2:

- Client send HTTP GET request to Real Server

- Real Serve send back to Client with "Proxy-Connection: keep-alive"

The following is the Ethereal data

Etherreal Frame: From Client to Real Server

Hypertext Transfer Protocol

GET http://www.xxxxxxxx.co.jp/img/yyyy.gif HTTP/1.0

Request Method: GET

.

Proxy-Connection: Keep-Alive

.

Etherreal Frame: From Real Server to Client

Hypertext Transfer Protocol

HTTP/1.1 200 OK

Response Code: 200

Proxy-Connection: keep-alive <<<---- here

.

I don't know whether this differentiation is a reason for this problem, however I would like to

clear this question for further investigation.

Your information would be greatly appreciated.

Best regards,
