URL tag of struts2 tag

The following are common usage of struts2 labels:
<S: URL value = "/images/copyright.jpg"/>
<S: URL action = "list" namespace = "/qxgl"/>
Note: The default value of the includeparams attribute in the URL is get. if a new value is specified in XML, all static files referenced using URL tags will carry the parameter values passed through the get method.
In addition, the attribute values of includeparams include none and all.
ALL: Add parameters in get and post to URL parameters.
;
None does not add parameters to the URL;

For example, you write data in detail. jsp

<Link href = "<s: URL value ="/CSS/styleqxgl.css "/>" rel = "stylesheet"
Type = "text/CSS">

Enter http: // localhost/detail. jsp in the browser? Id = 5

<Link href = "/Web Application name/CSS/styleqxgl.css? Id = 5 "rel =" stylesheet"
Type = "text/CSS">
In this example, styleqxgl.css is downloaded. If your system is deployed on the Internet, the bandwidth cost is very expensive. Using browser cache can effectively use bandwidth and save costs.

There are two solutions to this problem: <s: URL value = "/CSS/styleqxgl.css" includeparams = "NONE"/>

The other is configured in struts. xml. For details, refer to the following:
