Sander Temme, You are the skilled person in the art of Apache. After I changed html code "<p>" by "\n", the header error is gone. My C++ script were running OK in both IE and Firefox if I only have "cout" for printing outputs. Therefore I had a popup windows which asked me to download my test1.exe file in CGI-BIN folder when I only used Firefox, not IE. I had no error on exe file when I added "cout " to print two lines below: // #!C:\Perl\bin\per / /use CGI; So my question is what is the proper HTTP header to run my test1.exe in Firefox? Thank you for your helps. Can Le Sander Temme <[EMAIL PROTECTED]> wrote: > [EMAIL PROTECTED] http://www.temme.net/sander/ > PGP FP: 51B4 8727 466A 0BC3 69F4 B7B8 B2BE BC40 1529 24AF
