Hi Tomas,

    The preprocess() function always calls htmlheader() before
includehtml(). At this point no header was sent (because the page was
never processed) and the htnlheader() function would always send the
Content-type header.
	Yes.  What is the problem with that?  Could you send us
an example?

I've written a Lua module with functions that are to be called from a Lua page. The first thing the Lua page does is 'cgilua.doscript "./lib/colablib.lua"' (I couldn't get require to import a module not in the standard path) and then comes some static content. The problem arises when the page receives "action=save" as an argument; in this case the code in colablib.lua is supposed to save some data to disk and redirects to cgilua.script_vpath again with "action=view". But as Content-type was already sent by CGILua, my Location header is rendered useless.

--- BEGIN CODE ---
       cgilua.doscript "./lib/colablib.lua"
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
<html xmlns="";>
       <title><?lua= colab.currentPage() ?> -
                       <?lua= colab.wikiName() ?></title>
<meta name="generator" content="ColabWiki <?lua= colab.version() ?>" />
       <h1 id="header"><?lua= colab.currentPage() ?></h1>

       <div id="content">
       <?lua= colab.getContent() ?>
--- END CODE ---
