Well, the malformed/premature end pretty much means that it doesn't like what you are outputting before the HTML.
There are three things I'd try:
- VERY IMPORTANT! Use SetOption("ASCII","ON"). The headers *must* be in ASCII (possibly even 7bit), and as we know KiXtart defaults to unicode.
- Write to a log file or something to ensure that the script is actually being called - there may simply be an error in the path / filename substitution semantics. Normally using the "#!" magic will cause the input to be piped to the command, and as we know KiXtart does not accept piped input. To avoid this, rather than using the "#!" magic you should use a "handler", defined in the Apache configuration. Define a "handler" for files with a ".kix" extension and away you go.
- Rather than using "?" for the line feeds with the headers, explicitly send the end of line character using Chr(). I can't remember if it is Chr(10), Chr(13) or both off the top of my head.
If all that fails, you could of course call the script from a DOS batch file. Not pretty, but it may get you started.
It's been a while since I looked at this, so if you need more detail let me know.

quote:
what comes to ascii... think that 3.47 has no setoption
That may explain the difference in error messages between the two versions.
Which version of Apache are you running?

Ok, just downloaded Apache 2.0.47 and tried.
It works, but is a little kludgy.
First of all, you need to add a handler for KiXtart. Edit the httpd.conf file, search for the "AddHandler" lines and insert these:
code:
# KiXtart handler
AddHandler KiXtart .kix
Action KiXtart /cgi-bin/exec_kix.bat
What this does is say that whenever a file with the ".kix" extension is requested, run the handler instead. The requested file name is passed as an environment variable.
Now, in your cgi-bin directory, create a batch file called "exec_kix.bat". This is the handler script. WARNING You should probably create this script elsewhere, to avoid hackers running arbitrary code.
Here is a very simple example:
code:
@echo OFF
echo Content-Type: text/html
echo.
if exist kixoutput.txt del kixoutput.txt
kix32.exe "%PATH_TRANSLATED%"
if exist kixoutput.txt type kixoutput.txt
if exist kixoutput.txt del kixoutput.txt
This expects your KiXtart script to write it's output to "kixoutput.txt". In a real environment you need to do something a bit more clever to ensure that two requests don't overwrite the file. You could use the REMOTE_ADDR and REMOTE_PORT environment variables to create the temporary file name.
Here is a demonstration kixtart script, which you should put in your htdocs directory:
code:
Break ON
$gNULL=SetOption("ASCII","ON")
$gNULL=SetOption("WrapAtEOL","ON")
$gNull=RedirectOutput("kixoutput.txt")
"<HTML>" ?
"<HEAD>" ?
"<TITLE>KiXtart as CGI demonstration</TITLE>"
"</HEAD>" ?
"<BODY>" ?
"Using KiXtart version "+@KIX+" as CGI!" ?
"</BODY>" ?
"</HTML>" ?
Exit 0
Now, I call the page with URL http://127.0.0.1/kixdemo.kix the following string appears:
quote:
Using KiXtart version 4.20 as CGI!
It may be helpful to see all the environment variables, in which case write the following batch file to the cgi-bin directory:
code:
@echo OFF
echo Content-Type: text/html
echo.
echo ^<HTML^>
echo ^<HEAD^>^<TITLE^>DOS Batch as CGI^</TITLE^>^</HEAD^>
echo ^<BODY^>
echo ^<PRE^>
set
echo ^</PRE^>
echo ^</BODY^>
echo ^</HTML^>
When called with URL http://127.0.0.1/cgi-bin/env.bat you will get something similar to this:
quote:

Almost forgot, You may find with 3.47 that you don't need the RedirectOutput() kludge and temporary files to get it to work
