  3. <p class="wimscenter">Access restriction definition</p>
  4. <p>
  5.  
  6. This is multi-line data, executed line by line in their list orders. The
  7. restrictions only affect resource modules, but not administration modules.
  8. Lines starting with a `<span class="tt">#</span>' are comments.
  9. </p><p>
  10. Each line is of the format <span class="tt">[access conditions]:[host conditions]</span>.
  11. </p><p>
  12. The access conditions is a list of words, which will be ANDed. The available
  13. words are listed in the following table. Each word can be prefixed with
  14. <span class="tt wims_code_words">non</span> to reverse its logical meaning.
  15. </p>
  16. $table_header
  17. $table_tr<th>word</th><th>meaning</th></tr>
  18. $table_tr<td class="tt wims_code_words">class</td><td>The connection is within a virtual class.</td></tr>
  19. $table_tr<td class="tt wims_code_words">com</td><td>The requested module is under the com/ subtree.</td></tr>
  20. $table_tr<td class="tt wims_code_words">document</td><td>The requested module is a document. (not yet available)</td></tr>
  21. $table_tr<td class="tt wims_code_words">exercise</td><td>The requested module is an exercise.</td></tr>
  22. $table_tr<td class="tt wims_code_words">hint</td><td>The request is for hint.</td></tr>
  23. $table_tr<td class="tt wims_code_words">local</td><td>The requested module is under the local/ subtree.</td></tr>
  24. $table_tr<td class="tt wims_code_words">recreation</td><td>The requested module is a recreation.</td></tr>
  25. $table_tr<td class="tt wims_code_words">tool</td><td>The requested module is a tool.</td></tr>
  26. $table_end
  27.  
  28. The host conditions can be any host definition, eventually plus time
  29. definition as for any worksheets. If the first character of the host
  30. conditions is <span class="tt wims_code_words">!</span>, then the host/time meeting the conditions will
  31. be refused access (for the resources meeting the access conditions).
  32. Otherwise they will be granted access, and subsequent lines in the
  33. restriction definition will be ignored for those meeting the conditions.
