How to configure the web server redirector for multiple MobiLink servers?

Dear All

I would like to enquiry about redirector in web server (we are now testing
about synchronization through HTTP/HTTPS connection).

Here is the scenario:

We have an application which is running in two different regions, in
addition, they never cross synchronize to each other:
1. RemoteDB A, MobiLink Server A, Consolidated DB A
2. RemoteDB B, MobiLink Server B, Consolidated DB B

I have configure the redirector in IIS web server as (in redirector.config):

#MobiLink Server A
ML=10.0.0.1:80
#MobiLink Server B
ML=10.0.0.2:80

When I activate the synchronization from RemoteDB A, it works!
However, when I try it again from RemoteDB B, it is connected to MobiLink
server A. The synchronization is failed.
It seems that the redirector just pass connection to ML server in a listed
sequence.

Is there any advanced setting I can make the RemoteDB to recongize it's ML
server ? In other words, how to configure the web server redirector for
multiple MobiLink servers? Any pointer or information is much appreciated.

Thanks and Best Regards,
Jessica

I have not tried this, but I think this seems a reasonable experiment:

From the Help:
For ISAPI web servers:
exe_dir/iaredirect.dll/ml/

This is the url_suffix you supply in the REMOTE database.

Then you must add these entries in your redirector.config file in your
IIS directories:
SLEEP=1800
ML=myServ-pc:80
ML=209.123.123.1:8080
ML=myCompany.com:8081

The url_suffix ends in "ml", and the entries in the redirector.config
file begin with "ml".

I would suggest 2 changes. Make these all mla/MLA and mlb/MLB and see
what happens.

Make sure you remove the ML ones, so we do not confuse the issue.

Please let us know if this works.

Did this experiment work ? . Right now we have a simillar requirement to
host Mobilink redirection with Multiple Mobilink server connecting to
multiple consolidated DBs with a single webserver (Apache).

Which is the recommended way of doing this ? Any suggestions?

Thanks,
John Yovas
