This snippet removes the header and "chunk-length" from a &bvar containing the header and page content read from an http socket.


To Use: /ChunkFix &inputvaraible
alias ChunkFix {
if ($1 == &CF:Size) { echo -ac info2 * /ChunkFix: Input varaible cannot be "&CF:Size" | halt }
if ($1 == &CF:Head) { echo -ac info2 * /ChunkFix: Input varaible cannot be "&CF:Head" | halt }
if ($1 == &CF:Page) { echo -ac info2 * /ChunkFix: Input varaible cannot be "&CF:Page" | halt }
if (!$bvar($1,0)) { echo -ac info2 * /ChunkFix: Invalid varaible specified. | halt }

if ($bfind($1,1,$crlf $+ $crlf) == 0) return
bcopy &CF:Head 1 $1 1 $calc($v1 +3)
