• 結論

• The services that generate the two types of content are in different sites.
This merging of services and content from multiple web sites in an integrated, coherent way is called a mashup .

• If a web site uses data or functionality from another web site and combines it in an application, it's a mashup .
• If the application simply links to another site, for instance, through an HTML href link, it is not a mashup .
• There is some fuzziness in what constitutes a mashup and probably some degree of subjectivity too.

• The two primary mashup styles are server-side mashups and client-side mashups.

Mashup Styles (Server-side)
• Integrate services and content on the server.
• Acts as a proxy between a web application on the client, and the other web site that takes part in the mashup.
• All the requests from the client go to the server, which acts as a proxy to make calls to the other web site.

Mashup Styles (Server-side)

• Integrate services and content on the client.
• The client might make requests directly to the other web site.

Reasons for Using the Proxy Style
• A significant reason for using the proxy style is to overcome the constraints of the browser security sandbox and make XMLHttpRequests across domains.

Design Considerations in
Server-Side Mashups
• Security
• Ways to call the service
• The format of the response from the service
• Caching of results
• The need to modify the response
• Ways to handle exceptions and errors

結論
• 伺服器端 Mashup 對使用者負擔較少，不用受
限於用戶設備是否不完善，伺服器身為代理的
角色能夠替使用者呼叫其他服務並且合併，但
前提是伺服器是否做好了安全的防範。
• Mashup 應用範圍非常的廣，可以利用 API 將
網路上一些服務的內容，放置在同一個網頁中，
作為一個合併的效果， ex ： google map 、 yahoo 天氣、 youtube … 等等。
