Sticky sessions allow you to maintain the same IP address across multiple requests. To enable sticky sessions, include the session parameter after the username, followed by a randomly generated alphanumeric string. For example username-session-a1s2d3f4g5.
If your initial request is assigned proxy IP address 1.1.1.1, as long as you keep sending new requests with the same session ID, and that IP address is online and available, the system will route your queries through proxy IP address 1.1.1.1.
The length of time that a mobile IP address is available for use is variable. The availability duration you experience largely depends on carrier network settings, and how long the IP has been in the available pool if mobile IP addresses. In general, you can expect to be able to use an IP for about 5-10 minutes. If an IP becomes unavailable during your session, a new IP address is assigned automatically.
