Difficulty with cookies and setting login information

I am having difficulty using HTTP.jl to login to a page by passing the username and the password. This is the site’s HTML for the login form:

<form id="login_form" name="login_form" class="form-horizontal" method="post" novalidate action="https://site.com/login/try/id/normal">
   <div class="login_align">
   <fieldset id="inputs">
   <input id="email" name="email" type="text" placeholder="Email" autofocus required>
   <label for="email"></label>
   <input id="password" name="password" type="password" placeholder="Password" required>
   <label for="password"></label>
   <fieldset id="actions">
   <input type="submit" id="submit" value="Log in">

I used the command:

res = HTTP.request("POST", "https://site.com/login/try/id/normal", 

and get the response that all looks like the request passed

HTTP/1.1 200 OK
Date: Thu, 09 Jul 2020  04:0:0 GMT
Server: Apache/1.3.2 (Ubuntu)
X-Powered-By: PHP/6.0Ubuntu14.11
Set-Cookie: session_name=123987; path=/; HttpOnly

but subsequent calls all lead me to believe that it did not work, or that I am not using the state change saved. Subsequent calls produce the same as response as before without key login fields changing. Am I doing something wrong? Maybe the dictionary with the login details needs modification?
(I even tried to use a JSON instead via):

s = "{\"email\" : \"user@mail.com\", \"password\" : \"enter123\"}"
res = HTTP.request("POST", "https://site.com/login/try/id/normal", jj )

and the results do not indicate successful login

I tried just having cookies=true, So if cookies=Dict(name=>value) , should be set manually in subsequent requests, should
res_location_search = HTTP.request("GET", "https://website.com")
res_location_search = HTTP.request("GET", "https://website.com",cookies=Dict(name=>value))
if so, I got a response:

POST /login/try/id/normal HTTP/1.1
password: enter123
email: user@mail.com
Cookie: session_name=kog123321
Host: site.com
User-Agent: HTTP.jl/1.2.0
Content-Length: 0

then should the cookie be sent as
so that the request becomes?:
res_location_search = HTTP.request("GET","https://website.com",cookies=Dict("session_name"=>"kog123321"))

I tried this but still it does not change the state to logged in

it works with PyCall via:

import requests
ck = {'email': $(USER_NAME), 'password': $(PASSWORD)}
s = requests.Session()
r = s.post($(POST_LOGIN_URL), data=ck)
r2 = s.get($(MEMBER_URL))
r3 = r2.content
