in thread Enabling CGI Script from Apache's htdocs directory

Hi,

I've copied my hello.cgi to this directory /usr/local/apache/cgi-bin. And it works, thanks.

But my intention is to really access the cgi-bin from my htdocs/ directory. Like this:

htdocs-- |_Test |_cgi-bin/ | |_Webap1 |_ cgi-bin/ | |_Webap2 |_ cgi-bin/
Because there will be many webapps I need to build (hence many subdirectory other than "Test"). I've tried to modified the following httpd.conf entry:
#ScriptAlias /cgi-bin/ "/usr/local/apache/cgi-bin/" # into ScriptAlias /cgi-bin/ "/usr/local/apache/htdocs/cgi-bin/
But still unable to get it working. How can I enable it from this httpd.conf below?
# # This is the main Apache HTTP server configuration file. It contains + the # configuration directives that give the server its instructions. # See <URL:http://httpd.apache.org/docs/2.2> for detailed information. # In particular, see # <URL:http://httpd.apache.org/docs/2.2/mod/directives.html> # for a discussion of each configuration directive. # # Do NOT simply read the instructions in here without understanding # what they do. They're here only as hints or reminders. If you are +unsure # consult the online docs. You have been warned. # # Configuration and logfile names: If the filenames you specify for ma +ny # of the server's control files begin with "/" (or "drive:/" for Win32 +), the # server will use that explicit path. If the filenames do *not* begin # with "/", the value of ServerRoot is prepended -- so "logs/foo.log" # with ServerRoot set to "/usr/local/apache" will be interpreted by th +e # server as "/usr/local/apache/logs/foo.log". # # ServerRoot: The top of the directory tree under which the server's # configuration, error, and log files are kept. # # Do not add a slash at the end of the directory path. If you point # ServerRoot at a non-local disk, be sure to point the LockFile direct +ive # at a local disk.

    Check out the howto.

    -derby

    update: I'm not a apache 2.2 expert by anymeans but I think you're going to want something like this in your httpd.conf:

    <Directory /usr/local/apache/htdocs/*/cgi-bin> Options +ExecCGI </Directory>
    That being said ... I think one of the drawbacks to your approach is your exposing way too much of your underlying architecture. User's are going to see something like this:
    http://bioinfo-z.comp.nus.edu.sg/Test/cgi-bin/foo http://bioinfo-z.comp.nus.edu.sg/WebApp1/cgi-bin/bar http://bioinfo-z.comp.nus.edu.sg/WebApp2/cgi-bin/baz
    I think a better approach would be to either use virtual servers:
    http://test.comp.nus.edu.sg/cgi-bin/foo http://webapp1.comp.nus.edu.sg/cgi-bin/bar http://webapp2.comp.nus.edu.sg/cgi-bin/baz
    Or something like CGI::Application
    http://bioinfo-z.comp.nus.edu.sg/cgi-bin/test?mode=foo http://bioinfo-z.comp.nus.edu.sg/cgi-bin/webapp1?mode=bar http://bioinfo-z.comp.nus.edu.sg/cgi-bin/webapp2?mode=baz

    Because there will be many webapps I need to build (hence many subdirectory other than "Test"). I've tried to modified the following httpd.conf entry:
    #ScriptAlias /cgi-bin/ "/usr/local/apache/cgi-bin/" # into ScriptAlias /cgi-bin/ "/usr/local/apache/htdocs/cgi-bin/

    Note that there's the ending quote missing. But this modification would allow you to access scripts in /usr/local/apache/htdocs/cgi-bin/hello.cgi as

    http://bioinfo-z.comp.nus.edu.sg/cgi-bin/hello.cgi

    Try

    ScriptAlias /Test/cgi-bin/ /usr/local/apache/htdocs/Test/cgi-bin/ ScriptAlias /Webap1/cgi-bin/ /usr/local/apache/htdocs/Webap1/cgi-bin/ ScriptAlias /Webap2/cgi-bin/ /usr/local/apache/htdocs/Webap2/cgi-bin/

    inside your <IfModule alias_module></IfModule> block.

    You could also omit the cgi-bin part

    ScriptAlias /Test/ /usr/local/apache/htdocs/Test/cgi-bin/ ScriptAlias /Webap1/ /usr/local/apache/htdocs/Webap1/cgi-bin/ ScriptAlias /Webap2/ /usr/local/apache/htdocs/Webap2/cgi-bin/

    to access e.g /usr/local/apache/htdocs/Webap1/cgi-bin/hello.cgi as

    http://bioinfo-z.comp.nus.edu.sg/Webap1/hello.cgi

    --shmem

    _($_=" "x(1<<5)."?\n".q·/)Oo.  G°\        /
                                  /\_¯/(q    /
