My question is: When 2 users hit my flask page, does it get blocked until the first user finishes his request - it seems that the case. Is there a way to view the "queue" length? How is this queue maintained, or is it done by operating system networking stack?<span class="m_3493471057388347805HOEnZb"><font color="#888888"><br><div><div><br><div><br clear="all"><div><br></div>-- <br><div class="m_3493471057388347805m_-2288172528547955544gmail_signature">--- <span>Get your facts first, then you can distort them as you please.</span>--</div>
