Re: Adapter deployment and configuration

Tomas,

Thanks for the information, it did provide me answers to some queries. I
think I have mixed some terms in my earlier post so let me try again.

The application requires the ability to "pull" information from different
web sites as well the ability to support information "pushed" to it.

Your reply has provided me info. about the "push" part, where the users can
upload the information using IIS and the adapter.

The documentation on the internet suggests that the adapter can send data to
other URL's

Quote
Enables sending and receiving information by using HTTP. The BizTalk Server
2004 engine exposes one or more URLs to enable other applications to send
data to it, and it can use this adapter to send data to other URLs.

The questions that I had were:
- Can this adapter be used to pull information given a URL and not just send
data ?
- How does the component work (is it a standalone or part of the server) ?

I hope i have been able to explain my query.

Thanks,

Venky

Venky,

I am quite new to BizTalk and am currently evaluating it to find if it can
be used for the project that i am working on. Some basic questions that i
had:

- can a single http adapter instance be configured to retrieve information
from multiple URLs.

I'm not sure what you mean by "adapter instance". If you're talking about
receiving messages using the HTTP adapter, you need to understand that the
default receive-side HTTP adapter is a passive adapter: It does not query a
URL and get the messages from there, instead it sits in IIS on a web
directory you configure on your biztalk server and waits for incoming
connections from others POSTing messages to it. You can certainly have as
many HTTP Receive locations configured in separate URLs.

are adapters executables or are they components that run
within the server ?

The receive-side HTTP adapter is an isolated adapter implemented as an ISAPI
extension. it's a DLL you put in a virtual directory on IIS, and as such it
runs under IIS (usually an AppPool process in IIS6).

- can i run the adapter (http receive) on a separate box (dmz) than the
biztalk server ?

Not usually. The adapter requires access to the biztalk databases and the
ENTSSO, so normally you don't want to deploy that directly in the DMZ (your
network and security guys would have a fit as well) unless the entire
biztalk group was for external access and was entirely within the DMZ (not
common). One recommended way to get around this is in the biztalk
documentation: You put another application to receive the messages in the
DMZ that forwards the messages to your internal biztalk servers in the
protected corporate network. This could be a simple ASPX page, btw, so it's
not necessarily something fancy.
