Question about dynamic properties.

Hi guys,

I working on very important project and I need to make load tests for some services.

But I have collided with 2 major problems.


First:
I have a list with 100+ UIDs, but I won’t to create different 100+ http requests for this test.
Could you please share to me the instruction or example how to make this uid dynamic (see screenshot)?


Second:
I need to change some part of URLs in some http requests.
For example, marked by bold:

http:// localhost:5000/UserService.svc?m=Login&email=test1@gmail.com&password=11111
   
Is there a possibility to make dynamic URL per one http request? Or should I create separate request per one URL?


Thanks!
