HTTP 302 about rapache HOT 8 CLOSED

Redirects work fine in rApache. Not sure what you're doing, but this works with rApache handlers like so:

# Apache conf
<Location /test/relocation>
        SetHandler r-handler
        RFileHandler @DOCROOT@/relocation.R::handler
</Location>
</code>

and R code:

# relocation.R
handler <- function(){
   loc <- '/index.html'
   if (!is.null(GET) && !is.null(GET$loc) && GET$loc != '')
      loc <- GET$loc
   setHeader("Location",loc)
  return(HTTP_MOVED_TEMPORARILY)
}

from rapache.

Hmz maybe it is because I am still using rapache 1.14. Whenever I use setHeader, the HTTP 200 is already sent as it seems.

from rapache.

I updated to rapache 1.18 can't get it to work. I created a file /var/www/R-files/test.rhtml with the following content:

cat("This is a test!");
setContentType(type='text/plain')
setHeader("Location", "http://www.google.com");
return(HTTP_MOVED_TEMPORARILY);

Then when I download it with curl, I see a HTTP 200 instead:

curl -i http://127.0.0.1/R-files/test.rhtml
HTTP/1.1 200 OK
Date: Fri, 06 Apr 2012 17:54:46 GMT
Server: Apache/2.2.20 (Ubuntu)
Location: http://www.google.com
Vary: Accept-Encoding
Transfer-Encoding: chunked
Content-Type: text/plain

This is a test!

Get rid of the cat statement and it will work. Not sure about that HTTP
spec but if you're going to redirect the user to another url then they will
never see the request body anyway.

It doesn't work for me. Still get to see a HTTP 200, even without the text in the body.

What's your apache conf look like for this url?

I just used my debugging config:

<Directory /var/www/R-files>
    SetHandler r-script
    RHandler sys.source
</Directory>

and then /var/www/R-files/test contains:

setHeader("Location", "http://www.google.com");
return(HTTP_MOVED_TEMPORARILY)

from rapache.

Okay, I've figured out why: sys.source returns invisible() which
essentially returns NULL to rApache. Therefore rApache will always
returns DONE.

Easiest thing to do is create your own handler.
