What should I enter in mode=login?

Wrote a program under article delphisources.at.ua/publ/set_internet/raznye/prime...
everything works , but I don't know what to enter in the Data.Add('mode=login');
like the username is the user name ,but it is already entered in the user.
What a sniffer must be used when writing such programs?

Depends on the specific site. You need to examine your queries to see what, if and when passed.

What a sniffer must be used when writing such programs?

For HTTP use HTTPAnalyer'ohms.
For HTTPS use Fidller'ohms.
In difficult cases, the use of Wireshark.
In very difficult cases probressive sniffer packets from the router back to the computer,
directly in Wireshark.
I have HTTPAnalyer but I don't see where there is value to be transfered to this site . - Dominic_Spinka1 commented on July 2nd 19 at 18:07

About values if you're looking for a list of possible values... it's not anywhere except the server. Can of course all requests to the site to explore, climb on this site vbrowser, but why? Works fine. - abigail36 commented on July 2nd 19 at 18:10
