Examples of org.apache.wicket.request.target.coding.QueryStringUrlCodingStrategy

org.apache.wicket.request.target.coding.QueryStringUrlCodingStrategy

biv.com/protocols/uri/rfc/rfc3986.html">RFC 3986. This defines the URI standard, including query strings, and states that whereas the "path component contains data, usually organized in hierarchical form [divided by slashes]", the "query component [after the question mark] contains non-hierarchical data".

Findability. Public search engines prefer URLs with parameters stored hierarchically or in a shorter query string. Google's Design and Content Guidelines (as of May 6 2006) state: "Make a site with a clear hierarchy and text links. Every page should be reachable from at least one static text link. … If you decide to use dynamic pages (i.e., the URL contains a '?' character), be aware that not every search engine spider crawls dynamic pages as well as static pages. It helps to keep the parameters short and the number of them few."

The complexity of the parameters being passed. More complex parameters may make more sense expressed as a series of "key=value(s)" pairs in a query string than shoehorned into a hierarchical structure.

Regardless of which coding strategy is chosen for the mount, {@link org.apache.wicket.markup.html.link.BookmarkablePageLink BookmarkablePageLink} can be usedto insert a bookmarkable link to the request target.

This example demonstrates how to mount a path with QueryStringRequestTargetUrlCodingStrategy within the init method of a class implementing {@link org.apache.wicket.protocol.http.WebApplication WebApplication}:

mount(new QueryStringUrlCodingStrategy("/admin/productmanagement", admin.ProductManagement.class));

Note that, as with the main BookmarkablePageRequestTargetUrlCodingStrategy, if the output of this coding strategy is passed through {@link javax.servlet.http.HttpServletResponse#encodeURL(java.lang.String) HttpServletResponse.encodeURL} and the client has cookies turned off, the client's session IDwill be stored in a path parameter, like so:"/mywebapp/myservlet/admin/productmanagement;jsessionid=730EC527564AF1C73F8C2FB19B604F55?action=edit&product=4995" . @author Benjamin Hawkes-Lewis
