</pre></font>CGI has been the standard way of deploying web applications long before
ASP came along. In the CGI gateway world, CGI.pm has been a widely
used module in building CGI applications, and Apache::ASP is compatible
with scripts written with CGI.pm. Also, as of version 2.19, Apache::ASP
can run in standalone CGI mode for the Apache web server without
<a href=http://perl.apache.org><font size=-1 face=verdana><b>mod_perl</b></font></a> being available. See "Standalone CGI Mode" section below.
<font face="courier new" size=3><pre>
</pre></font>Following are some special notes with respect to compatibility with CGI
and CGI.pm. Use of CGI.pm in any of these ways was made possible through
a great amount of work, and is not guaranteed to be portable with other perl
ASP implementations, as other ASP implementations will likely be more limited.</font>

<font face=verdana><font class=title size=+0 color=#555555><b>Standalone CGI Mode, without mod_perl</b></font>
<font face="courier new" size=3><pre>
</pre></font>As of version 2.19, Apache::ASP scripts may be run as standalone
<a href=cgi.html><font size=-1 face=verdana><b>CGI</b></font></a> scripts without mod_perl being loaded into Apache. Work
to date has only been done with mod_cgi scripts under Apache on a
Unix platform, and it is unlikely to work under other web servers
or Win32 operating systems without further development.
<font face="courier new" size=3><pre>
</pre></font>To run the ./site/eg scripts as CGI scripts, you copy the
./site directory to some location accessible by your web
server, in this example its /usr/local/apache/htdocs/aspcgi,
then in your httpd.conf activate Apache::ASP cgi
scripts like so:
<font face="courier new" size=3><pre>
Alias /aspcgi/ /usr/local/apache/htdocs/aspcgi/
<Directory /usr/local/apache/htdocs/aspcgi/eg/ >
AddType application/x-httpd-cgi .htm
AddType application/x-httpd-cgi .html
AddType application/x-httpd-cgi .asp
AddType application/x-httpd-cgi .xml
AddType application/x-httpd-cgi .ssi
AllowOverride None
Options +ExecCGI +Indexes
</Directory>
</pre></font>Then install the asp-perl script from the distribution
into /usr/bin, or some other directory. This is
so the CGI execution line at the top of those scripts
will invoke the asp-perl wrapper like so:
<font face="courier new" size=3><pre>
#!/usr/bin/perl /usr/bin/asp-perl
</pre></font>The asp-perl script is a cgi wrapper that sets up the
Apache::ASP environment in lieu of the normal mod_perl
handler request. Because there is no Apache->dir_config()
data available under mod_cgi, the asp-perl script will load
a asp.conf file that may define a hash %Config of
data for populating the dir_config() data. An example
of a complex asp.conf file is at <a href=eg/asp.conf>./site/eg/asp.conf</a>
<font face="courier new" size=3><pre>
</pre></font>So, a trivial asp.conf file might look like:
<font face="courier new" size=3><pre>
# asp.conf
%Config = (
'Global' => '.',
'StateDir' => '/tmp/aspstate',
'NoState' => 0,
'Debug' => 3,
);
</pre></font>The default for NoState is 1 in CGI mode, so one must
set NoState to 0 for objects like $Session & $Application
to be defined.</font>
<p>
<a name=CGI.pm></a>
<font face=verdana><font class=title size=+0 color=#555555><b>CGI.pm</b></font>
<font face="courier new" size=3><pre>
</pre></font>CGI.pm is a very useful module that aids developers in
the building of these applications, and Apache::ASP has been made to
be compatible with function calls in CGI.pm. Please see cgi.htm in the
./site/eg directory for a sample ASP script written almost entirely in CGI.
<font face="courier new" size=3><pre>
</pre></font>As of version 0.09, use of CGI.pm for both input and output is seamless
when working under Apache::ASP. Thus if you would like to port existing
cgi scripts over to Apache::ASP, all you need to do is wrap <% %> around
the script to get going. This functionality has been implemented so that
developers may have the best of both worlds when building their
web applications.
<font face="courier new" size=3><pre>
</pre></font>For more information about CGI.pm, please see the web site

<font face=verdana><font class=title size=+0 color=#555555><b>Query Object Initialization</b></font>
<font face="courier new" size=3><pre>
</pre></font>You may create a <a href=cgi.html><font size=-1 face=verdana><b>CGI</b></font></a>.pm $query object like so:
<font face="courier new" size=3><pre>

</pre></font>As of Apache::ASP version 0.09, form input may be read in
by CGI.pm upon initialization. Before, Apache::ASP would
consume the form input when reading into $Request->Form(),
but now form input is cached, and may be used by CGI.pm input
routines.</font>

</pre></font>Not only can you use the <a href=cgi.html><font size=-1 face=verdana><b>CGI</b></font></a>.pm $query->header() method
to put out headers, but with the CgiHeaders config option
set to true, you can also print "Header: value\n", and add
similar lines to the top of your script, like:
<font face="courier new" size=3><pre>
Some-Header: Value
Some-Other: OtherValue
<html><body> Script body starts here.
</pre></font>Once there are no longer any cgi style headers, or the
there is a newline, the body of the script begins. So
if you just had an asp script like:
<font face="courier new" size=3><pre>
print join(":", %{$Request->QueryString});
</pre></font>You would likely end up with no output, as that line is
interpreted as a header because of the semicolon. When doing
basic debugging, as long as you start the page with <html>
you will avoid this problem.</font>

<font face=verdana><font class=title size=+0 color=#555555><b>print()ing CGI</b></font>
<font face="courier new" size=3><pre>
</pre></font>CGI is notorious for its print() statements, and the functions in CGI.pm
usually return strings to print(). You can do this under Apache::ASP,
since print just aliases to $Response->Write(). Note that $| has no
affect.
<font face="courier new" size=3><pre>
print $query->header();
print $query->start_form();

<a name=File%20Upload></a>
<font face=verdana><font class=title size=+0 color=#555555><b>File Upload</b></font>
<font face="courier new" size=3><pre>
</pre></font>CGI.pm is used for implementing reading the input from file upload. You
may create the file upload form however you wish, and then the
data may be recovered from the file upload by using $Request->Form().
Data from a file upload gets written to a file handle, that may in
turn be read from. The original file name that was uploaded is the
name of the file handle.
<font face="courier new" size=3><pre>
my $filehandle = $Request->Form('file_upload_field_name');
print $filehandle; # will get you the file name
my $data;
while(read($filehandle, $data, 1024)) {
# data from the uploaded file read into $data
};
</pre></font>Please see the docs on CGI.pm (try perldoc CGI) for more information
on this topic, and <a href=eg/file_upload.asp>./site/eg/file_upload.asp</a> for an example of its use.
Also, for more details about CGI.pm itself, please see the web site:
<font face="courier new" size=3><pre>
<a href=http://stein.cshl.org/WWW/software/CGI/>http://stein.cshl.org/WWW/software/CGI/</a>
</pre></font>Occasionally, a newer version of CGI.pm will be released which breaks
file upload compatibility with Apache::ASP. If you find this to occur,
then you might consider downgrading to a version that works. For example,
one can install a working CGI.pm v2.78 for a working version, and to
get old versions of this module, one can go to BACKPAN at:
<font face="courier new" size=3><pre>
<a href=http://backpan.cpan.org/modules/by-authors/id/L/LD/LDS/>http://backpan.cpan.org/modules/by-authors/id/L/LD/LDS/</a>
</pre></font>There is also $Request->FileUpload() API extension that you can use to get
more data about a file upload, so that the following properties are
available for querying:
<font face="courier new" size=3><pre>
my $file_upload = $Request->{FileUpload}{upload_field};
$file_upload->{BrowserFile}
$file_upload->{FileHandle}
$file_upload->{ContentType}
# only if FileUploadTemp is set
$file_upload->{TempFile}
# whatever mime headers are sent with the file upload
# just "keys %$file_upload" to find out
$file_upload->{?Mime-Header?}
</pre></font>Please see the $Request section in <a href=objects.html><font size=-1 face=verdana><b>OBJECTS</b></font></a> for more information.</font>
