GoServe news - changes by version
This page summarizes the changes made in each new release of GoServe,
starting from release 2.00 (the first HTTP/1.0 version).
For full details on each change, please see the
online reference or GOSERVE.DOC.
2.40 [27 June 1995]
- Dynamic document creation allows data to be sent to client
incrementally. Dynamic documents are started by the SEND command, and
ended by SEND COMPLETE. All completion commands (FILE, VAR, STRING,
etc.) may be used within a dynamic document without closing
the connection. SET NETBUFFER OFF may be used to request immediate
transmission of data to the client.
- A simple 'server push' example of a dynamic document has been added
to GOFILTER.80 and the 'Test and control' sample page.
- New WAIT command lets a filter sleep conditionally for a time.
- Query/Extract TRANSACTIONS returns the number of transactions since
reset.
- Query/Extract ELAPSED returns the elapsed time for the current
transaction.
- Operational improvements:
- More 'business as usual' network errors are audited as 'N' lines
rather than as Errors.
- Audit 'C' lines now have a consistent format (sent bytes and times
are always included).
- After being changed, the primary filter will be reloaded after the
server has been idle for ten seconds (was variable).
- HALT or timeout in second-level filter will not cause GoServe to
report failure.
- File command caching now works for GOPHER protocol as well as HTTP.
2.32 [25 May 1995]
- New GoRemote pages provide full Options Notebook function, driven
remotely or locally from any forms-capable Web client.
- New GOREMOTE.80 filter (used for GoRemote) provides samples of
efficient forms processing and 'server-side includes' into the GoRemote
pages.
- New VAR command allows a document or other data to be sent directly
to the client from a Rexx variable (avoiding the need for a temporary
file). 2.32 extends this to arbitrary length data (>32K TCP/IP limit).
- 'Limits exceeded' count is now separated from error counts (that is,
if a timeout or other limit is exceeded, it does not show as an Error).
QUERY/EXTRACT LIMITCOUNT provides access to this count. Limits exceeded
are audited as 'L' lines (rather than 'E').
- New SET, QUERY, and EXTRACT commands, and EXTRACT() function. These
allow access to some dozens of internal GoServe state settings.
- Optional FILE command caching. This allows repeated simple FILE
requests to avoid the call to the filter. This reduces response time to
15ms or less for the sample home page (on a 486/33MHz).
- Network wait times are excluded from Response time measurements.
This makes Response time a more useful indicator of server load and
performance.
- Multiple IP support. GoServe can now support multiple LAN adapters;
the IP address and SERVERNAME reflect which address the client has
connected to.
- Enhanced DATADIR checking (settings that are not a valid directory
will not be accepted).
- Internal changes to improve control and performance; improvements to
documentation, etc.
2.10 [23 Mar 1995]
- The first argument string passed to the filter now includes the port
of the remote client, following the address.
- New CLIENTNAME() function retrieves the name of the remote client.
- Performance improvements and better handling of overload conditions.
2.00 [14 Feb 1995] - initial HTTP/1.0 release.
