Redirect Question
Hi
I have a problem, I'm using HttpClient to connect to a website. The
intial page contains a redirect, I think through JavaScript, which spawns a new
browser. I need to get to the ne wbrowser to login. The initial HttpClient invocation return a status code 200, I don't even see the
3xx redirect code never mind the Response's Location value.
Any ideas?
Thanks

If this is the case, you should be able to request the included javascript
source file from the web server just as you would any other file, either
using HttpClient, or using your own browser (if you don't expect the
JavaScript file to change much). Then you can read the redirect location
from the contents of the JavaScript file.

Thanks for the reply, unfortunately I can't see the Javascript content since it's loaded
as a JavaScript source file. Do I have any other options.
Thanks

Hi Ed,
It depends on the content of the page returned. You can look at the
actual content returned (which should contain the JavaScript), and parse out
the redirect location. It may look something like this:
self.location.replace("/app/self-registration");
Then you can do a GET or POST (using HttpClient) to the redirect URL (which
may be relative, as in the example above). Hope this helps.

Question about cookies and Netscape-Enterprise/6.0 server
Posted by Chris Lamprecht <cl...@elitemail.org>.
I'm using HttpClient 2.0-final to do a form-based login to a
Netscape-Enterprise 6.0 server (according to the HTTP headers). It uses
cookies to maintain the session.
When I run HttpClient in RFC2109 cookie mode, it works fine. However, when
I switch it to either compatibility or NETSCAPE_DRAFT mode, the server seems
to ignore the cookies that HttpClient sends it. (The server acts like the
client isn't logged in).
I used Mozilla's LiveHTTPHeaders plugin to see what Mozilla sends when I log
in using Mozilla , and the Cookie: header line is as follows:
Cookie: NSC_vuejsfdu_443=c0a8061300bb;
FC=AQEBBwID6QIQRUYzQjVGQjIxxEYzNEY0OQMJY2wxMCAgICAgBAoxMDg0OTQ5Mzk0BQ02Ni4yN

PDLK=NONE; DOC=/registrar/reg/Pregistration.WBX
(That should all be on a single line).
The only difference I can see in HttpClient's wire log is that it puts one
cookie per line, and it doesn't end each cookie with a semicolon:
>> "GET /registrar/reg/Pregistration.WBX HTTP/1.1[\r][\n]"
>> "Accept: image/gif, image/x-xbitmap, image/jpeg, */*[\r][\n]"
>> "Accept-Language: en-us[\r][\n]"

>> "Cookie: NSC_vuejsfdu_443=c0a8061301bb[\r][\n]"
(Note: I am intentionally setting the headers to appear like a normal
browser; that's why it says MSIE for User-Agent)
Any ideas why the server only recognizes RFC2109?
This isn't necessarily a big problem for me, since RFC2109 works, but I'm
trying to emulate a browser as _exactly_ as possible. Thanks for your help.
Chris
