I am creating a linux web server, and would like to call some linux command through html.
I am using FORM to create it, below is my code: ----------------------------------------------------- <html> <body> <FIELDSET> <LEGEND>Command Line Input</LEGEND><P> <FORM ACTION="/cgi-bin/webserver" METHOD="POST"> <P>Please type your linux command (80 chars max.):<BR> <INPUT NAME="data" SIZE="60" MAXLENGTH="80"><BR> <INPUT TYPE=SUBMIT VALUE="Send"> </FORM> </FIELDSET> </body> </html> ----------------------------------------------------- My webserver is compiled from C code. After I enter the linux command to the command field and then hit Send, it will clear the existing webpage and return the result. How can I modified the html, so that the result return to a table / field in the existing webpage? |

How can I do the following in C:
---------------------------------------------------------------- #!/bin/sh # do processing (or launch it as background job) echo "HTTP/1.0 204 No Change" echo (as non-NPH, you'd simply replace HTTP/1.0 with the Status: CGI header). ---------------------------------------------------------------- How to replace HTTP/1.0 with status : CGI header? In the beginning of my c file, I do the following and doesn't work: system("echo HTTP/1.0 204 No Change"); system("echo"); |

Have you tried
CODE printf("HTTP/1.0 204 No Change\n\n") ? What kind of programming experience do you have? |

Very little in html.
After using printf("HTTP/1.9 204 No Change\n\n"), firefox behaves differently than internet explorer. Firefox sends data to a new page. However, in internet explorer, it does not send data to new page, but I cannot see the data in the same webpage either. My plan is to display the result to a box in the send page. |

HTML isn't programming. It's just markup.
You really should learn basic programming in C before you start CGI programming in C. CGI programming adds another layer of complexity that someone who doesn't understand basic programming isn't ready for. |

Can you provide the URL (address) of a document that demonstrates the problem?
