I'm trying to create a WebDav folder that can host a pdf file for shared review and comment. I'm running into a strange issue. If I add a * handler for webdav module reviewers can submit comments on off line files that get written to the server, but they don't sync down to other reviewers. However this handler prevents pdf files, or any file for that matter, from opening. If I remove the handler, website functions as normal, pdfs can be opened, but essentially WebDav is disabled and the directory is undected by acrobat.
