Looking at the source of the page, the sign-in form has the following  
pertinent fields --

	<input type="text" name="email" maxlength="100" value="" style="width: 
120px" class="textfield">
	<input type="password" name="password" maxlength="64" value=""  
style="width:120px" class="textfield">
									
The field names that would be passed as the POST are 'email' and  
'password'. Now, I don't know what command{} definitions you have for  
check_http or how they're configured so I'll show you how to create a  
new one very specific to this test --

define command {
	command_name 		check_flowers_login
	command_line		$USER1$/check_http -I $HOSTADDRESS$ -H  
ww12.1800flowers.com -u /signin.do -P  
"email=svenugopaal at gmail.com&password=podhum"
}

Set that as the check_command for a service associated with the host  
and nagios will verify that the web server does not return an HTTP  
error after login. Note that if your server returns a standard 200  
response indicating OK even if there is a login error (most likely),  
you'll want to identify a word or string of text that should appear in  
the page after successful login, but not for a failure, and look for  
that with the -s parameter --

define command {
	command_name 		check_flowers_login
	command_line		$USER1$/check_http -I $HOSTADDRESS$ -H  
ww12.1800flowers.com -u /signin.do -P  
"email=svenugopaal at gmail.com&password=podhum" -s "you are logged in"
}

My charge is 1 local specialty beer for all Hand Holding Help.
