And what about 'request->requestvb->val_len' ?
Does that hold the length of the correct string,
or the "extended" one?

But was 'request->requestvb->val_len' 3, or 7?

Remember that the request->requestvb->val.string buffer is
*not* a null-terminated string. It's only the first
'request->requestvb->val_len' characters that are valid.
You should ignore everything else.

Copy the string using

strncpy( my_buffer, request->requestvb->val.string,
request->requestvb->val_len);

*not*

strncpy( my_buffer, request->requestvb->val.string,
strlen(request->requestvb->val.string));
or
strcpy( my_buffer, request->requestvb->val.string );
