Web Server Application Cookie Encoding

[3ddark 3]

I am having problems with the Delphi Web Server Application.
I create a cookie and set it as a value

The cookie value comes as ELEKTRON%C4%B0K from the browser.

LCookValues.AddPair('name', 'ELEKTRONİK');
Response.SetCookieField(LCookValues, HOST_ADDR, '/', IncDay(Now, 15), False);

 

When I use it with Base64 encoding, the encoding result is RUxFS1RST07EsEs=

But the result on the browser is RUxFS1RST07EsEs%3D

TNetEncoding.Base64String.Encode('ELEKTRONİK')

 

The place where the characters are broken is in the function below. How can I fix this situation?

procedure TIdHTTPAppResponse.MoveCookiesAndCustomHeaders;
.....
begin
...
LDestCookie.Value := DoHTTPEncode(LSrcCookie.Value);
...
end;

When I test Base64 encode/decode online from any site, the extra characters give incorrect results.

 

When I want to use this cookie in other requests, I use it as follows.

TNetEncoding.Base64String.Decode(Request.CookieFields.Values['name'])

As a result, the information I receive is ELEKTRONİK7 This is not my correct information.

TNetEncoding.Base64String.Decode(TNetEncoding.URL.Decode(Request.CookieFields.Values['name']))

Use like this working. But constantly converting things is a waste of time.

Where am I going wrong? There must be an easier way.

Other web tools do not have any of these problems. We can solve all web processes very easily.
