captcha.module is the basic CAPTCHA module, offering general CAPTCHA
|

administration and a simple math challenge.
|

Installation:
|
| 10 |
|
|
Installation is like with all normal drupal modules:
|
| 11 |
|
|
extract the 'captcha' folder from the tar ball to the
|
| 12 |
|
|
modules directory from your website (typically sites/all/modules).
|
| 13 |
|
|
|
| 14 |
|
|
Dependencies:
|
| 15 |
|
|
The basic CAPTCHA module has no dependencies, nothing special is required.
|
| 16 |
|
|

Conflicts/known issues:

|
CAPTCHA and page caching do not work together currently.
|
| 19 |
|
|
However, the CAPTCHA module does support the Drupal core page
|
| 20 |
|
|
caching mechanism: it just disables the caching of the pages
|
| 21 |
|
|
where it has to put its challenges.
|
| 22 |
|
|
If you use other caching mechanisms, it is possible that CAPTCHA's
|
| 23 |
|
|
won't work, and you get error messages like 'CAPTCHA validation
|
| 24 |
|
|
error: unknown CAPTCHA session ID'.
|
| 25 |
|
|

|
|
Configuration:
|
| 27 |
|
|
The configuration page is at admin/config/people/captcha,
|
| 28 |
|
|
where you can configure the CAPTCHA module
|
| 29 |
|
|
and enable challenges for the desired forms.
|
| 30 |
|
|
You can also tweak the image CAPTCHA to your liking. |
