For information about other properties, see News Tile.

For recommendations about how to maintain Portal performance when configuring News iViews, see 2260754 Information published on SAP site .

Name	Description
Article Refresh Interval	Controls the rate at which the News iView requests new content from the article feeds. You set the default value by using SAP NetWeaver Administrator to configure the com.sap.portal.httpconnectivity.urlfetcherservice.expirationTimeOut property in the URLFetcherService portal service.. Example To set a default article refresh interval of 15 minutes, enter `900000` (number of seconds plus three zeroes) in the Value column of the com.sap.portal.httpconnectivity.urlfetcherservice.expirationTimeOut property. For more information about configuring portal services, see Accessing Portal Services in SAP NetWeaver Administrator.
Use Server-Side Cache	Server-side caching uses a shared cache of the fetched content so that if multiple users request it again, the proxy can return the response without needing to access the Web server of the article feed. This decreases server load and removes storage bottlenecks. The default value is True.
Fetch Mode	Determines how the portal page builder handles the retrieval of data from the article feeds of a News iView. The values of this property are: Client-Side or Server-Side. The default value is Client-Side. Client-side fetching supports the retrieval of article feeds directly by the client browser. Server-side fetching supports the retrieval of article feeds by submitting the client request to the portal server, which then makes the request to retrieve the content from the content source. This method uses the portal server caching mechanism Caution When the fetch mode is set to Server-Side, a high number of article feeds can adversely affect feed server response times due to the additional request between the portal server and the content source. For the maximum recommended number of article feeds, see 2260754 . When the fetch mode is set to Client-Side, the proxy settings of the client browser are used. When the fetch mode is set to Server-Side, the proxy settings of the portal server are applied instead (see Defining a Proxy Server for the Portal). To prevent iView runtime errors, make sure the proxy settings are defined either on the portal server or user browsers, or both.

Use Server-Side Cache

Server-side caching uses a shared cache of the fetched content so that if multiple users request it again, the proxy can return the response without needing to access the Web server of the article feed. This decreases server load and removes storage bottlenecks.

The default value is True.

Fetch Mode

Determines how the portal page builder handles the retrieval of data from the article feeds of a News iView. The values of this property are: Client-Side or Server-Side.

The default value is Client-Side.

Client-side fetching supports the retrieval of article feeds directly by the client browser.

Server-side fetching supports the retrieval of article feeds by submitting the client request to the portal server, which then makes the request to retrieve the content from the content source. This method uses the portal server caching mechanism

Caution

When the fetch mode is set to Server-Side, a high number of article feeds can adversely affect feed server response times due to the additional request between the portal server and the content source. For the maximum recommended number of article feeds, see 2260754 Information published on SAP site .

When the fetch mode is set to Client-Side, the proxy settings of the client browser are used. When the fetch mode is set to Server-Side, the proxy settings of the portal server are applied instead (see Defining a Proxy Server for the Portal). To prevent iView runtime errors, make sure the proxy settings are defined either on the portal server or user browsers, or both.
