# gets SSLPassPhrase by file instead of promt for |
| 98 |
|
| 99 |
Every start of apache require to enter the password for the above generated SSL key. |
| 100 |
This can be annoying if you plan some automatic restart of apache. |
| 101 |
There is a way to automatically give the password to apache with the option: |
| 102 |
|
| 103 |
SSLPassPhraseDialog exec:/path/to/your_password_programm |
| 104 |
|
| 105 |
But it's upt to you to write the password programm, be careful!! |
| 106 |
Some times, it is easier to simply protect a non protected file, than writing a programm that gives a password!! |
| 107 |
Easiest way would be e.g. |
| 108 |
|
| 109 |
#-----------your_password_programm --------- |
| 110 |
#!/bin/sh |
| 111 |
echo <your passphrase> |
| 112 |
#------------------ end snip ---------------------- |
| 113 |
|
| 114 |
chmod 700 /path/to/your_password_programm |
| 115 |
chown www-data.www-data /path/to/your_password_programm |
| 116 |
|
| 117 |
|
| 118 |
But again, this would be very unsecure!!! |

- edit /etc/init.d/apache: |

| 130 |
replace start-stop-daemon --start --pidfile $PIDFILE --exec $DAEMON |
| 131 |

# Relative HTTP/HTTPS switching |

Switch from HTTP to HTTPS and vice versa by using only relative URLs |
| 149 |
Benefit: Absolute URLs are avioded and this way the website is more flexible |
