I ran into something today I've never noticed any comment here about.
Maybe I should know this but never ran into it before.
I wanted to use a single cgi script to generate several different
formated pages. That is, the output page would have different
ordering depending on the content of ENV{SCRIPT_FILENAME}.
I hoped to have one real cgi script and several symbolic links to it
that would change that ENV item.
I tried the simplist test at www.jtan.com/~reader/scr_filename.cgi which
outputs the SCRIPT_FILENAME ENV item of the contacting client, by
creating `ln -s link.cgi scr_filename.cgi'
I assumed it would fire scr_filename.cgi but with a different
ENV{SCRIPT_FILENAME}. But apparently that isn't going to work.
Trying www.jtan.com/~reader/link.cgi
Gives an error in the browser window: Internal Server Error
And this in apache error log:
Premature end of script headers: /home/reader/public_html/link.cgi
An ls -l shows:
-rwxr-xr-x 1 [...] 202 Apr 1 2002 scr_filename.cgi
[...]
lrwxr-xr-x 1 [...] 8 Jan 23 09:19 link.cgi -> diag.cgi
scr_filename.cgi contains:
#!/usr/bin/perl
print "Content-type: text/html\n\n";
print "SCRIPT_FILENAME = $ENV{SCRIPT_FILENAME}";
