Hello,

I’m interested in ASA (Adaptive Server Anywhere) built-in
web server. Maybe some of you have experience developing
applications based on ASA web server or have some knowledge
on such implementations.

I have in mind creating fully functional web site using only
ASA capabilities. It means that all web site contents are
generated in DB and are transferred to end user via HTTP or
HTTPS.

Another possible solution, which I’m interested in, is
creating multi tier system, where DB is generating XML,
passing it to middle tier via ASA web server, where it is
parsed and converted to HTML. In this case ASA web server is
accessible only in LAN with purpose to secret DB structure
and business logics from third party developers, giving them
only standard structure XML for developing middle tier.

I want to know how reliable ASA web server for this kind of
solutions is, how many connections can it process, etc. For
example, can it process 1000 simultaneous requests not
counting LAN users (via TCPIP)?
Considering second case, I have in mind the possibility of
limiting XML size (lets say to 100KB) in order to decrease
network loads.

I would be very grateful for any kind of help.

The objective of implementing HTTP support in ASA was primarily to provide
support for web services interfaces, it was not to compete with pure web
servers such as IIS or Apache. As a database server we have done benchmarks
with customers where the server supported 1400 concurrent users and approx.
4200 concurrent connections (3 connections per user). However you should
note that that benchmark was not done over HTTP.

The approach you described of using an application server talking to ASA
through XML web services would be one common approach to building a web
application that relies on a backend database server.
