rtcHTTPClient and REST

[ClementDoss]

Hi,

I'm working on a rtc REST server and I need a better understanding of how I should write my ClientApp to connect the best way. I want to use the least resources while keeping optimal performance. I don't want the client app to stop being responsive.
How should I design in a multi-threaded client application. For example: Let's say there are 2 forms in my client application. Each of them need to request some data from the server:
1) Can I centralize rtcHTTPClient? In that case, is it possible to use only one rtcHTTPclient for the entire application? Is there a need for rtcHTTPClient Pool?
Or
2) Should every form has it own rtcHTTPClient

Do you have an example or some articles to suggest?

TIA,
Clément

There is no "one-for-all" answer to that question. It all depends on your Applications requirements. While a single TRtcHttpClient will be enough for most Applications working with a single Server, you would need a separate TRtcHttpClient component if your Client has to periodically poll the Server for data, like in the RTC Messenger Client and Server Demos. Also, please note tha using more connections does not automatically give you better response, if all your connections will be sharing the same bandwidth and talking to the same Server.

Sorry for taking so long to answer...

There will be one client application, and one server application. The client application will not use modal windows. Every "Toolbutton" on the client form will be linked to an "action" (ex: /customer/function/1234). Some actions might return a dataset with a few rows ( less then 50 ). Some actions will instruct the server to perform some update or delete. For those, the server will return immediately while all the work is done in the background.
Since the user can click one button at a time, I'm considering to have only one rtcHttpClient for the entire client application. The calls to the server should be very quick for most forms on the application. For the forms that might request more data and that might take some time to return,  I'll use another rtcHTTPclient.

The application will deal with customer, suppliers, orders, etc. For now I don't think "RTC messenger like" will be needed, although it is quite possible to implement such messenger in a future release.

TIA,
Clément

Sounds like you've answered your question
