I am writing an app which will display articles at a membership based website. 

We want the app to be able to read and display articles that are set as "members only" - even if the app owner is not a member. 

So I want to be able to login without showing the app user any user or password info. 

When I try to access a members only article , I get a redirect, but I do not get an authentication challenge. 

Any ideas how I can get my app to login automatically? 

Here's what the form looks like. Do I have to include all of the input values in my POST request? 

```
<FORM ACTION="https://www.mysite.com/cgi-bin/mysite/process" METHOD=POST>
<input type="hidden" NAME="mv_todo"  VALUE="return">
<input type="hidden" name="mv_session_id" value="DySUxWM5">
<INPUT TYPE="hidden" name="mv_success_variable_hash" VALUE="">
<INPUT TYPE="hidden" name="mv_success_variable_hash_colon" VALUE="">
<INPUT TYPE="hidden" NAME="mv_successpage" VALUE="index">
<input type="hidden" name="mv_failpage" value="login">

Please make sure that it is not empty.'); this.focus();this.select();return false; }; " type="text" size="15"></td></tr>

<tr><td colspan="2"><input value="" name="login_complete_param" type="hidden"> <input value="Continue..." name="ig_click form-method:continue" type="submit" class="coolButton"></td></tr>
</table>
<p ></p>

</form>
