Hi,

I need to create something like this:

\<?xml version="1.0" encoding="UTF-8"?\> aQlfVHX+qPM 2009-09-19T08:14:55Z

The response should contain the next headers:

Content-Type=`application/vnd.3gpp+xml`  
Authentication-Info={rspauth=`xxxxxxxxxxx...xxxxxxxxxxx`,qop=`auth-int`,cnonce=`xxxxxxxxxxxxxxxxxx....xxxxxxxxxxxxx`,nc=`000 00001`}

How can I do that?

I always see {“Cache-Control”=\>“no-cache”,  
“Content-Type”=\>“application/xml”}  
when I print the headers…

I can use xml builder ok to generate the xml, but I have the problem  
with the headers.

Thanks.

You should just be able to set headers[‘foo’] in your controller.

Thanks Fred!  
Yeah I’ve tried several ways. Now I’ve managed to get:

{“Cache-Control”=\>“no-cache”,  
“Authentication-info”=\>“rspauth=`xxxxxxxxxxx...xxxxxxxxxxx`,qop=`auth-int`,cnonce=`xxxxxxxxxxxxxxxxxx....xxxxxxxxxxxxx`,nc=`00000001`”,  
“Content-Type”=\>“application/xml”}

I still have problems with the content-type and getting rid of  
cache-control headers.

For the content-type I’ve tried:

response.content\_type = “xxxx” and headers[‘Content-type’] = “xxxx” but  
still get always the “default” one. Haven’t yet really tried to get rid  
of the cache-control.

The response is generated like:

respond\_to do |format|  
format.xml  
end

Thanks.
