HTTP persistent connection

[Lucas]

I tried it but:

unused, m_hi ------> Error: Failed to create thread __Http_PostWithTimeout. Max 1000 threads allowed.
m_hitop -----------> Error (RT) in Http.PostWithTimeout: Exception 0xC0000005. Access violation. Cannot read memory at 0x0. In at 0x0 (0x0+0x0).

Can you modify Http.PostWithTimeout?
