HttpRequest returning protected values

[pendal]

I am working on loggin into an internal site automatically and performing a search.

currently we do this with a perl script so I know it is possible.

in order to do this correctly on the system I am working with I need to do the following

1. login to site
2. receive and set a cookie from the system
3. perform search

I have logged into the site but when I do I receive the following response.

HttpMessage Object
(
    [type:protected] => 2
    [body:protected] => 
    [requestMethod:protected] => 
    [requestUrl:protected] => 
    [responseStatus:protected] => Moved Temporarily
    [responseCode:protected] => 302
    [httpVersion:protected] => 1.1
    [headers:protected] => Array
        (
            [Date] => Tue, 14 Jul 2009 13:19:27 GMT
            [Server] => Apache/2.0.52 (CentOS)
            [Cache-Control] => private
            [Expires] => -1
            [Set-Cookie] => Array
                (
                    [0] => JSESSIONID=7E91F42DB9AF8C2A121B53F3357F47CD; Path=/docushare
                    [1] => AmberUser=64.862793904806DB19D7179E6935BF6A434FB36C7DE65E8479873BC31AF0705F0F21.-2uuosmbjw4ozfx4nh09b; Path=/docushare
                )

        [Location] => http://blue/docushare
        [Content-Length] => 0
        [Content-Type] => text/plain; charset=UTF-8
    )

[parentMessage:protected] => 
)

the Set-Cookie array is what I need to access, but the object is protected. I do NOT need to change the value, I just need to get it and load it into a variable in my script.

how do i get to that array.

there is one other issue here i think. Generally when you log into this site, you see the page that returns this information for a second and then it redirects you to the home page.

I'm not sure if that counts for anything, but i wanted to pass it along.

any help would be great.

Thanks,
C
