Constructor Detail

UrlHandler

public UrlHandler(javax.servlet.http.HttpServletRequest req,
                  boolean relative)

If relative we assume urls are relative to the host + port. Internally we need to strip off the host + port + context.

Parameters:

req - the incoming request

relative - true for relative urls

UrlHandler

public UrlHandler(String urlPrefix,
                  String context,
                  boolean relative)

Parameters:

urlPrefix - Usually host + port + "/" e.g. example.com:8080/

context - null, zero length or the servlet context, e.g. caldav

relative - true if we want relative (to the server) urls

Method Detail

prefix

public String prefix(String val)
              throws WebdavException

Description copied from interface: UrlPrefixer

Return an appropriately prefixed url. The parameter url will be absolute or relative. If relative it may be prefixed with the context path which we need to remove.

We're doing this because some clients don't handle absolute urls (a violation of the spec)
