# URL In the second section, we will determine to which URL Infoport will listen. [![url.png](https://doc.eainfoport.cz/uploads/images/gallery/2022-06/scaled-1680-/url.png)](https://doc.eainfoport.cz/uploads/images/gallery/2022-06/url.png) - - - - - - ***TLS*** If you are using secure communication, it is possible to choose the TLS version(s) that you consider secure enough. For example, version 1.1 is not supported on Windows operating systems after 2021 and should not be used. [![tls url.png](https://doc.eainfoport.cz/uploads/images/gallery/2022-05/scaled-1680-/tls-url.png)](https://doc.eainfoport.cz/uploads/images/gallery/2022-05/tls-url.png) - - - - - - The *URL* consists of three parts. The first one specifies the protocol (http or https); the second one is the IP address, and the third one is the port. If we want to use https (see below), the certificate must be issued to the same IP address as specified here.

The user only needs to configure the Http1 protocol, which supports the operation of Windows Authentication.

Some requests may contain large amounts of data and Infoport cannot process them. (*For example, an OpenID login where all the groups the user is in are sent*). ***[![url max request.png](https://doc.eainfoport.cz/uploads/images/gallery/2022-06/scaled-1680-/url-max-request.png)](https://doc.eainfoport.cz/uploads/images/gallery/2022-06/url-max-request.png)*** - - - - - - If you want another URL to which the portal will listen, press the [![add-row.png](https://doc.eainfoport.cz/uploads/images/gallery/2022-04/scaled-1680-/add-row.png)](https://doc.eainfoport.cz/uploads/images/gallery/2022-04/add-row.png) button and new items will be created to fill in. To delete a URL, press the button [![delete url.png](https://doc.eainfoport.cz/uploads/images/gallery/2022-05/scaled-1680-/delete-url.png)](https://doc.eainfoport.cz/uploads/images/gallery/2022-05/delete-url.png).
