Hi Tomas, Tomas wrote:
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.
