• ... - an arbitrary number of name,value parameter pairs that will be url-encoded and added to the url. The special parameter name '#' is reserved for specifying an anchor. e.g. getScriptUrl('x','y','view','#'=>'XXX',a=>1,b=>2) will give .../view/x/y?a=1&b=2#XXX

• $key - name of value stored in session to be cleared. Note that you cannot clear AUTHUSER.

checkTopicEditLock( $web, $topic, $script ) -> ( $oopsUrl, $loginName, $unlockTime )

• $script The script to invoke when continuing with the edit

redirectCgiQuery( $query, $url, $passthru )

• $passthru - enable passthrough.

Return: none

Print output to STDOUT that will cause a 302 redirect to a new URL. Nothing more should be printed to STDOUT after this method has been called.

The $passthru parameter allows you to pass the parameters that were passed to the current query on to the target URL, as long as it is another URL on the same TWiki installation. If $passthru is set to a true value, then TWiki will save the current URL parameters, and then try to restore them on the other side of the redirect. Parameters are stored on the server in a cache file (see {PassthroughDir} in =configure).

Note that if $passthru is set, then any parameters in $url will be lost when the old parameters are restored. if you want to change any parameter values, you will need to do that in the current CGI query before redirecting e.g.

my $query = TWiki::Func::getCgiQuery();
$query->param(-name => 'text', -value => 'Different text');
TWiki::Func::redirectCgiQuery(
  undef, TWiki::Func::getScriptUrl($web, $topic, 'edit'), 1);

• registered tags are evaluated at the same time as system tags, such as %SERVERTIME. commonTagsHandler is only called later, when all system tags have already been expanded (though they are expanded again after commonTagsHandler returns).
• registered tag names can only contain alphanumerics and _ (underscore)
• registering a tag FRED defines both %FRED{...}% and also %FRED%.
• registered tag handlers cannot return another tag as their only result (e.g. return '%SERVERTIME%';). It won't work.

The symbols %USERSWEB%, %SYSTEMWEB%, %DOCWEB%, %MAINWEB% and %TWIKIWEB% can be used in the input to represent the web names set in $cfg{UsersWebName} and $cfg{SystemWebName}. For example:
