[pmwiki-users] Have a canonical url declaration : how to ?

[Petko Yotov]

Add this in config.php to insert a canonical link in the page header:

   if ($action == 'browse')
    $HTMLFooterFmt['canonical'] = '<link rel="canonical" 
href="{$PageUrl}" />';

If your wiki is accessible both through HTTP and HTTPS, you should 
select one of those and set correctly the $ScriptUrl variable.

I'm not sure what you mean by 'have such canonical thing if "action" 
pages'.

If you want to set as canonical the base "browse" URL on ?action=edit, 
diff, upload, print and other action pages, remove the first line above.

If you want to set the action URL as a canonical URL, add after the 
above lines:


   else $HTMLFooterFmt['canonical'] =
     '<link rel="canonical" href="{$PageUrl}?action='.$action.'" />';

Note that search engines and bots are usually blocked when they try to 
access ?action=edit and similar pages.

All these canonical urls will not work well for pages where you have 
(:pagelist ... request=1:) or if you use a recipe like HttpVariables or 
MultiLanguage that take information from the URL to display different 
content. (But neither will FastCache.)
