check_http --url and --string don't work together?

I can't seem to use --url and --string together. Url seems to make it 
not bother checking the string.

First I test the --string works as follows:

check_http -S -H www.somedomain.com --string='<html blah blah <title> 
The Wrong Nonexistent Web Page</title>...'

which returns as expected. This is what I want to make sure it will warn 
me if it isn't finding exactly what I expect.

CRITICAL - string not found|time=0.210894s;;;0.000000 size=6403B;;;0


But if I do

check_http -S -H www.somedomain.com --url="/some/path/" --string='<html 
blah blah <title> The Wrong Nonexistent Web Page</title>...'

I get

OK - HTTP/1.1 302 Found - 0.110 second response time 
|time=0.110347s;;;0.000000 size=690B;;;0


It doesn't check the string! Instead it just says that because some page 
was directed to that everything must be ok... ie False Positive.


The bigger picture:

I am trying to do testing of an https login page and get into a website. 
This requires that I log in via ssl and supply a username and password. 
The problem is that the login page will redirect to somewhere regardless 
of the result. If the login is successful you can get the internal pages 
and if unsuccessful it redirects to another login page. So I really need 
to get --url and --string working together to check the actual html.

I know there is webinject but I'd rather stick to check_http, it's much 
more straight forward and webinject's dependencies failed to install 
yesterday so I'd rather do this than bother fixing that just to try it.


Any ideas on getting this url and string business to work together?
