- August 29, 1995 - Chicago, IL. Today, IT Solutions announced the
- availability of free demonstration copies of WebRex, the custom HTTP
- server that provides easy access to objects. Objects can be developed and
- deployed on HP-UX, SunOS, Solaris, Digital UNIX, NEXTSTEP, and soon
- Windows NT. The Web Rex server turns requests for URLs as they enter the
- server into messages to specific objects. These objects perform their
- work aided by classes in the WebRex library and return a page of HTML to
- the client. These objects can be existing objects linked with an existing
- relational database.
-
- "Many IS managers are feeling pressure to establish a corporate presence
- on the Web. While this pressure contributes to Web growth, it does not
- necessarily contribute to content quality. The WebRex server was
- developed to make Web sites compelling by linking the server directly to
- data and thus linking the business directly to the customer." says WebRex
- Product Manager Paul Gerard.
-
- "The processing of the WebRex server is quite simple: Each time an HTML
- browser makes a request, an existing Web Rex sub-process is called to
- service that request. After a request has been serviced, the
- sub-processes stay alive for a configurable period of time. Thus, these
- new processes can be re-used by new requests caching whatever the applets
- deem necessary (for example; database connection state). An application
- can be entirely distributed and arbitrarily complex, as complex as any
- object-based application." says WebRex Project Manager Drew Trieger.
-
- In the three WebRex demonstrations on the IT Solutions Web site
- (http://www.its.com), all database accesses are toward an Oracle7 database
- running on a Solaris 2.3 Sun Sparc machine. Though we have used Oracle7,
- Web Rex does not limit you to the database. With Web Rex, there is a
- level of abstraction between the database and the application code so that
- a variety of relational databases could be used with little change to the
- source code. For example, if we wanted to use Sybase, we would simply
- tell the application to use the Sybase database adaptor instead of the
- Oracle database adaptor and then mimic the same database structure in the
- Sybase database. This change results in little or no source code changes,
- adding greater flexibility to applications developed using Web Rex. There
- are existing database adaptors for DB2, Sybase, Oracle, AS/400, Cincom
- Supra, DRNA, Gupta SQLBase, INFORMIX, MDI, NCR Teradata, O2 OODBMS,
- QuickBase, and Microsoft SQL Server making it possible to use your
- existing relational database to serve the Web.
-
- Web Rex is a very high performance server, even when linked to a database.
- Database connection state can be automatically cached by the Web Rex
- applets so that only the first HTTP request requiring a database
- connection incurs the overhead of connecting to the database. All
- subsequent requests efficiently share this connection. Performance is only
- limited by the database's ability to serve query requests and the network
- bandwidth of the machine's connection to the Internet. Web Rex is not a
- bottleneck. Since CGI-BIN scripts are not used in this demo, there is no
- overhead in creating and tearing down processes on the Web Rex server.
- Requests enter the "object" domain from the "web" domain very quickly,
- there is no need to fork or run scripts.
-
- The WebRex demonstration server software is available today through
- anonymous FTP from ITS. This version runs on NEXTSTEP and will expire on
- September 30, 1995.
