How to create a page that unsets a cookie, then redirects via Location: header?

I need to create a page, well, I suppose it’s a non-page of sorts, which unsets a cookie, does a small amount of other PHP processing, and then redirects to a new URL via the Location: header. There will be no actual page output as such whatsoever.

Is there an easy way to do this in MODx? The difficulty of course is that cookie-handling and header-setting both need to be done before there is any page output whatsoever.

Alternatively, I suppose I could create the php script as an actual page in the filesystem: is there somewhere I should put such a page, and anything I would need to set up in MODx to prevent it from trying to process the URL as if it were a MODx "Friendly URL" belonging to an actual MODx page?

Thanks for any advice.

hi,

well, the simplest way to do this is to create a page/ressource that you do not display in the menu and call a snippet in this page that will do the job

i use that kind of page quite often (for ajax for example) and, to make it easier, i use minimal template as the page template, set the wysiwyg on no in the page and simply write my snippet call in the content textarea, done!
(minimal template is just a blank template with [*content*] then no html output or else before your cookie/session or header tricks)

when it comes to the page url you can either use an alias if you’re using url_rewriting or simply [~n~] n being the page index
