RE: Multiple requests to a webservice...???

Hi Srishti,

From your description, you have an IIS ISAPI component which accept request
from client and perform some processing and write the output back to
client. Now, you're looking for a way to make multiple such requests(http)
package into a single http request so that you can make multiple such web
request called without establishing multiple http connections, correct?

If this is the case, I think this is mostly depending on the server-side
ISAPI processing code logic. For http/soap protocal, the standard is fixed
that we cannot make multiple http request become a single request(something
like batch request sending). However, for server-side processing, that's
customizable. For example, you may make your ISAPI extension accept an
additional parameter such as processing count so as to determine how many
times you will need to process for the same requests. Or you can define new
request message formatting so as to contain multiple method call bodies in
it. Anyway, I think it is necessary to adjust the server-side code logic.
How do you think?

Sincerely,

Steven Cheng

Subject: Multiple requests to a webservice...???

Hi all,
I don't know if this is the right place to ask this question.... so if it
isn't please direct me as to where I should be asking this....

I have an ISAPI dll for a client (written in c++ compiled in VS2003)
This application handles one request at a time, does some calculation and
returns the result on the browser. This is being hosted on my server which
the client calls from his server.

Now, my client needs to do this operation from the ISAPI dll multiple
times
for every user who makes a request for it.
So this process takes a considerable amount of time for each user as it
performs the operation manu times for evry user.

"one request takes about 0.6-0.7 seconds and 12 requests take 7-10
seconds.
Could it be possible do something so that we need to send just one http
request instead of 12. Something like a SOAP api where we can pass data
(whether in array or XML) of all the 12 requests at one time and you can
return the result?"

I have been looking into this past two days in the general area of XML
webservices, ATL server, .NET web services.... But not sure what to do
ye...

I hope I am clear... and hopefully heading in the right direction... If
so,
I didn't find any indication/examples of how I could pass multiple
requests
to a webservice method....
Hopefully I can make a web service or picksup data from an XML file and
return the results in an XML files as well of all the requests....(don't
know
what is possible!!)


Please help...............!!!
Regards & Thanks a lot
Srishti
