.Varbuffsize R/O Property (32-bit Platforms Only)
|Top Previous Next|
Working with HTTP Variables explains how the build-in HTTP server works, and how the VAR buffer is used to receive HTTP variables.
Buffer capacity can be changed through the sock.varbuffrq. Sock.varbuffrq requests buffer size in 256-byte pages, whereas this property returns buffer size in bytes.
Relationship between the two is as follows: sock.varbuffsize=num_pages*256-33 (or =0 when num_pages=0), where "num_pages" is the number of buffer pages that was GRANTED through the sock.varbuffrq. "-33" is because this number of bytes is needed for internal buffer variables.
This property is only available on 32-bit platforms.
