Answer Section

Try first without reading follows.
Read the online manual and find the way.

CGI

In the <Directory .../www/htdocs> section, put these override directives:
```
   AllowOverride Options FileInfo
```
You must restart httpd after httpd.conf is edited:
```
   $ www/bin/apachectl restart
```

In htdocs/netex/.htaccess:

   Options +ExecCGI
   AddHandler cgi-script .cgi

test.cgi example:

   #!/sw/bin/python
   # -*- coding: utf-8 -*-
   import cgi

   req = cgi.FieldStorage()
   who = req.getvalue('who', '')
   print "Content-Type: text/html; charset=utf-8"
   print
   if who:
       print """<html>
   <head><title>Hello</title></head>
   <body>
   %s さん、こんにちは！
   </body>
   </html>
   """ % cgi.escape(who)
   else:
       print """<html>
   <head><title>Input your name</title></head>
   <body>
   <form method="POST" action="test.cgi">
   お名前をどうぞ
   <input type="text" name="who" />
   <input type="submit" value="送信" />
   </form>
   </body>
   </html>"""

SSI

Override ... the same as in CGI

In htdocs/netex/.htaccess, add:

   Options +Includes
   AddType text/html .shtml
   AddOutputFilter INCLUDES .shtml

test.shtml example:

   <html>
   <head>
   <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
   </head>
   <body>
   Now the time is <!--#echo var="DATE_LOCAL" -->.<br>
   <!--#config timefmt="%Y/%m/%d %H:%M:%S" -->
   Or, <!--#echo var="DATE_LOCAL" -->. <br>
   只今の時刻は
   <!--#config timefmt="%Y" --> <!--#echo var="DATE_LOCAL" -->年
   <!--#config timefmt="%m" --> <!--#echo var="DATE_LOCAL" -->月
   <!--#config timefmt="%d" --> <!--#echo var="DATE_LOCAL" -->日
   <!--#config timefmt="%H" --> <!--#echo var="DATE_LOCAL" -->時
   <!--#config timefmt="%M" --> <!--#echo var="DATE_LOCAL" -->分
   <!--#config timefmt="%S" --> <!--#echo var="DATE_LOCAL" -->秒です。<br>
   あなたは <!--#echo var="REMOTE_ADDR" --> から
   <!--#echo var="HTTP_USER_AGENT" --> で、アクセスしています。
   <pre>
   <!--#exec cmd="export LANG=ja_JP.UTF-8; cal" -->
   </pre>
   </body>
   </html>

Basic Authentication

In the <Directory .../www/htdocs> section, put these override directives (add AuthConfig):
```
   AllowOverride Options FileInfo AuthConfig
```
Restart httpd (as in CGI)

Use this command to create a password file:

   $ cd ~/www/htdocs/netex
   $ /sw/www/bin/htpasswd -c .htpasswd me

In htdocs/netex/.htaccess, add:

   AuthType Basic
   AuthName "Restricted Area"
   AuthUserFile htdocs/netex/.htpasswd
   Require valid-user

Access test.cgi or test.shtml and confirm that password is requested.

Security Consideration

HTTP Authentication

Example (in HTTP header):

   Authorization: Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==

With Python:

   >>> import base64
   >>> base64.decodestring('QWxhZGRpbjpvcGVuIHNlc2FtZQ==')
   'Aladdin:open sesame'

Not encrypted !

Report

Write a mail report to Kikuchi (in Japanese).
Copy the access records from logs/access_log (only for the successful ones of CGI, SSI and Basic Authentication).

Additional Notes

File system to URL mapping

DocumentRoot: ~/www/htdocs -> http://localhost:8080/
ScriptAlias: ~/www/cgi-bin/ -> http://localhost:8080/cgi-bin/
A directory under DocumentRoot: ~/www/htdocs/netex -> http://localhost:8080/netex/
