I have to make authenticated get requests, and I am having issues using HTTP.jl. I am getting an authentication error. In the Python Requests package I would programmatically login and then pass my requests like:

```julia
response = requests.get(ags_url, params, cookies=session.cookies)

```

Below are the headers I received after I authenticated:

> 13-element Array{Pair{SubString{String},SubString{String}},1}:  
> “Date” =\> “Mon, 29 Apr 2019 18:27:36 GMT”  
> “X-Powered-By” =\> “Servlet/3.0”  
> “P3P” =\> “CP="IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT"”  
> “Pragma” =\> “no-cache”  
> “Cache-Control” =\> “no-store, no-cache, must-revalidate, private, proxy-revalidate”  
> “X-XSS-Protection” =\> “1; mode=block”  
> “X-Content-Type-Options” =\> “nosniff”  
> “SSO\_STATUS” =\> “ParseOutput”  
> “Content-Length” =\> “148”  
> “Set-Cookie” =\> “JSESSIONID=0000MPoGXgudavv3ci0bUklNt-I:-1; Path=/; HttpOnly”

> “Content-Type” =\> “text/xml;charset=UTF-8”  
> “Content-Language” =\> “en-US”

Do I need to pass the Set-Cookies similar to:

```julia
url = "http://fakeurl/app?"
cookies = Dict(headers[10])
query = (_f1 = "C", _FC = "Change", _EVT = "CHG", _RTN = "MSG", _LFN = "ALL", _PDL = "DEV", _TKN = "IC16.1", _f3 = "Shares")
response = HTTP.get(url; query = query, cookies=cookies)

```

I am getting a bad requests error. I guess I am am having trouble understanding the HTTP package after using Requests for so long. Can anyone help?

Just FYI, you can use requests via PyCall.

If you don’t need to modify the cookies you should be able to just use the default cookie jar without needing to pass them back on every request.

```julia
HTTP.request("GET", "http://httpbin.org/cookies/set?test=1"; cookies = true)

```

After the request the cookies are stored in `HTTP.CookieRequest.default_cookiejar`

```julia
Dict{String,Set{HTTP.Cookies.Cookie}} with 1 entry:
  "httpbin.org" => Set(HTTP.Cookies.Cookie[Cookie("test", "1", "/", "httpbin.org", 0001-01-01T00:00:00, 0, false, false, true, String[])])

```

You can use your own jar by passing a `Dict{String, Set{Cookie}}` on the `cookiejar` argument.

```julia
jar = Dict{String, Set{HTTP.Cookie}}()
HTTP.request("GET", "http://httpbin.org/cookies/set?test=1"; cookies = true, cookiejar = jar)

```

**Note:** There’s a bug in `v0.8.0` which causes an error when just passing `cookies = true` and you might need to pass a non-empty `Dict{String,String}`.

```julia
HTTP.request("GET", "http://httpbin.org/cookies/set?test=1"; cookies = Dict{String,String}("type" => "quadruplechocchip"))

```

It’s fixed on the `master` branch.

benelsen,

Thank you for the detailed response! I do have http.jl version 0.8.0 and am receiving an error when I try and use the cookies = true argument. From a high-level perspective, once I log in I receive a sessionID (token) for my session that must be passed on each subsequent transaction. So, can i just use the default cookie jar? Or said another way, will this library keep track of these cookies for me and pass them back on each HTTP.request, or will I need to manually set the cookies via the following command?

```julia
Dict{String,Set{HTTP.Cookies.Cookie}}

```

thanks!

If the server returns a `Set-Cookie`header, like in your original post, you should just be able to just use the default cookie jar, but you do need to enable cookie support on each request with `cookies = true` (or the workaround above in v0.8.0).
