Web Server/400 allows symbolic links inside the document hierarchy. Symbolic links to files outside the hierarchy are allowable as long as the Server User Profile has *RX permission to the file and *X permission to all directories in the file's real path. For files in the QDLS file system, the Server User Profile must have *USE permission to all the directories in the file's real path and to the file itself.
Symbolic links to files in QSYS are allowed for source
physical files and program-described physical files containing a single
field. However, in order for a symbolic link to successfully follow a link
to a QSYS object, the link can only be the last element in the URL. For
example, if the path
/link/ is a symbolic link to
/qsys.lib/wwwsamples.lib/, then a request for the Web document
/link/ would return a dynamic index of
/qsys.lib/wwwsamples.lib/. But, a request for the Web
/link/SampleDoc.file would not work because the
symbolic link in this path is not the last element of the URL
Very long paths in the Root file system can be supported by using shorter symbolic links that point to deeper paths.
