Question

I have two questions I hope I can get an answer for with regard to my service oriented application

1. I am creating a service oriented application where controls have no events, it’s all done by calling services… that means the service url is written in my jQuery code, but this seems somehow not nice…. It’s like what is the best option to save service urls?! I feel it’s hard to maintain and not secure when it’s written inside the page or inside javascript referenced file.

2. I am talking to a hosting company and they told me that I can host this application services on cloud server and the application on another servers…. not all in the same server, but my application services are self hosted, I mean the services are inside the application…. so to make things work as my hosting company wants, shall I host the restful services in IIS or how exactly?

Answer 1

1. Service URL must be in your page or script source file. It can be local address unless you are using cross domain calls and JSONP – cross domain calls requires absolute address. It is the same as any other web technology. If you want navigation to other page, you must provide URL. If you want some picture or css file you must provide URL. Security is up to you.
2. This will be the problem of cross domain calls. Normally JS calls can be done only to the same domain where the page is exposed. Once the application server is exposed on different domain name your calls will not work. To avoid that you must use JSONP (WCF 4 has support for that). Exposing rest services consumed by your application from self hosted application is strange. REST services are consumed by your clients – they are front-end services and should be part of your application hosted on front-end web server. Your back-end application server should not host anything directly accessible by your clients.
