Hi, as the statement, I am trying to do a ping testing page by using AJAX. my intention is the xmlHttp could receive each printf("...") from CGI individually and successively, and then update the content of the testing page. Unfortunately, it only receives all data after the CGI program is terminated.
The web-server is BOA. I just started to learn AJAX,therefore don't fully understand the procedures.
Please let me know how you guys achieve the similar objectives or any special requirements for web-server to support?
Thanks in advance.

Hi

I really don't know about Ajax and CGI scripts. But remember stdout is buffered by default in C programs. Maybe add a "fflush(stdout)" after the printf? It might not work since the web server can do buffering as well, but it might be worth a try.

Hi Guttorm,
Yes,it works now. thank you very much for your hints. Actually I finally found something called "server push" technology, and it perfectly suits my needs.guess what? I found the "fflush(stdout)" in all the CGI samples.
