Question
HTTP Headers (@sethttpheader("Location"; "http://somenewlocation")
I'm playing around with this to do some redirection in a form:
a field containing is located at the top :
@if( something ;
@sethttpheader("Location";
Now this works 'sometimes' , but not all the time... I suppose because the HTTP Response code is not changed properly from 200 to 306...
The HTTP headers are there on the response from the server, it just doesn't work ....
So how could I do this - it's supposed to be a simple solution, preferably in @formula's . Any ideas ?
cheers,
Tom

Edit html attributes and in the HTML Head content, give a meta tag something like this:
<META HTTP-EQUIV="REFRESH" CONTENT="0; URL=http://www.bozzie.com"

And you don't want to use standard redirection using HTTP-Equiv or JavaScript? You say, the second time the header contains the Location, but the browser doesn't respond on it? What's the difference between the first and the seconf header? Caching problem on either side? Do you also use other settings, such as Last-Modified or so? You can look at the ldd/performance documents, e.g. WebApps_caching.pdf, it describes some of the techniques "they" use in R6.

hmm redirection needs to be hidden, why don't u write a webqueryopen(if efficiency doesn't matter that much) and do a location.replace for the $$htmlhead field...
BTW ur question made me to read abt HTTP headers and redirection , most of them talk only about location , let me know if u find out any...
Partha
The HTTP-EQUIV doesn't work because MS removed it in I think IE5 and up. You could try sending a real refresh header.
A more Domino-ish way would be to open your forms (>OpenDocument) and documents (?EditDocument, ?OpenDocument) via an agent. The agent takes params, tests conditions, and redirects either to the "expected" form/document, or else it redirects to you alternate. Two problems with this method:
1) redirect ALWAYS occurs, instead of only for special conditions (normal condition produces redirect to the form or document)
2) bookmarks
A similar workaround might use a frameset. The framset consists of a single frame, computed URL, with a default target of _parent. The redirect calculation takes place in the formula. Downsides:
1) user never gets to see a true URL
2) also effectively does a "needless" redirect for normal conditions, as the form has to load in the frame
3) bookmarks are unlikely to be a problem, but... a) MS does this weird thing with bookmarking framesets, not sure how the interaction will work, and b) users CAN right click in the frame and choose to bookmark
Re: your 200 v. 306. 306 has been deprecated. 303 and 307 are the normal redirects.
OK, thanks all of you, I really hoped someone to come up with a wonder solution (because I think using the HTTP headers would be a very nice solution for redirecting - I really am too lazy to write an agent :-) )
But it's la dolce Italia for me now - 3 weeks well-earned (or whatever) holiday ... yey.
cheers,
Tom
Unfortunately, the response code is not considered a standard header...
HTTP/1.1 200 Document follows

The response code is merely the second word of the first line of the response. It would indeed be nice if there was still some way to set that.

Actually, it works for the first connection, when a user authenticates himself for the first time. Then afterwards, he just continues (although the headers are sent to the browser)
