| 28 : | ** Optimisation component. $this->SEF_SPACE should be set to the | ||
| 29 : | ** character that is to replace blanks in names that form the URL. | ||
| 30 : | ** You can vary this, although the only sensible choices seem to be | ||
| 31 : | ** underscore or hyphen (_ or -). | ||
| 32 : | ** | ||
| 33 : | ** The arrays $this->custom_code and $this->custom_name must be kept exactly | ||
| 34 : | ** in step with each other. $this->custom_code is a list of the components | ||
| 35 : | ** that are to be handled by ReMOSef. | ||
| 36 : | ** | ||
| 37 : | ** The array $this->custom_name is the alternative name that will be used | ||
| 38 : | ** in the optimised URL to identify the component and can be whatever | ||
| 39 : | ** you please so long as it is unique and legal for a URL. Apart from | ||
| 40 : | ** using the custom name for the component, ReMOSef will do no further | ||
| 41 : | ** translation of the URL than is done by the standard Mambo SEF - UNLESS | ||
| 42 : | ** there is a sef_ext.php file installed for that component. The | ||
| 43 : | ** exception to this is ReMOSitory - the optimisation code for Remository | ||
| 44 : | ** is integrated in ReMOSef. For other components, if a sef_ext.php is | ||
| 45 : | ** present, it will be invoked by ReMOSef. | ||
| 46 : | ** | ||
| 47 : | |||
| 48 : | ** The array $remosef_content_task is capable of translating the tasks | ||
| 49 : | ** understood by the Mambo content component. Please DO NOT CHANGE what | ||
| 50 : | ** is to the left of the equals sign. When putting different values on | ||
| 51 : | ** the right hand side, remember that they must all be different, and must | ||
| 52 : | ** also be different from any of the custom names used for components. | ||
| 53 : | ** Without that, Remosef cannot figure out what a SEF URL means and will | ||
| 54 : | ** give unpredictable results. | ||
