bad TCP ack from client to HTTP server

[Z. V]

Hello,

I wrote a win32 HTTP server which handles GET requests from chrome browser.

After few files served OK, I got the attached packets in Wireshark.

The file I sent is ~1MB.

192.168.14.48: Client (chorme)

192.168.14.69: Server

Can you please tell why ?

Should I change TCP window ? How ?

When I wrote the same sequence in C#, it worked OK.

Thank you,

Zvika
