Can I manually make tcp zero window and drop?

Question

I have to request specific directory repeatedly. ex) https://example.org/home/dir/aaa/11 There is case if http response status code is 200 or else. If 200? read data from raw socket&and if there is 404, drop remainder packets. ex

    int bytes_received = SSL_read(ssl, response, 1370);
    printf("%s\nreceive : %d", response, bytes_received);
    if(strstr(response, "HTTP1.1 200 OK") goto(specific behavior);
else{drop; goto(ssl_write)}; // goto first send point, I want to drop remainder packets in kernel buffer from this point.  
    puts("");

Is this possible by manually modifying Kernel, or tcp structure or size of sliding window? Or else? If can't, then why? Thx.
