Re: WebBridge

Mieko, Bernadette,

I think it is indeed possible to establish article-level links to sites 
such as Wiley and ScienceDirect via CrossRef without losing the WAM 
connection for off-campus users. At least, initial testing seems 
promising. Here is what I have done:

1) Include the proxy in your syntax when linking to CrossRef. For 
example, we use:
http://0-doi.crossref.org.mercury.concordia.ca/resolve?pid=<username:password>&aulast=#@AULAST#&issn=#@ISSN#&volume=#@VOLUME#&issue=#@ISSUE#&spage=#@SPAGE#&date=#@YEAR#

2) Add the following two entries to your WAM table:
*.crossref.org
*.doi.org
That way, when you move from whatever (proxied) origin to CrossRef to 
your target (eg. Wiley or ScienceDirect), you will consistently stay in 
WAM territory, so to speak. Therefore, it is not necessary for CrossRef 
to transfer the proxy information per se; as long as you always stays 
within sites that are included in your WAM table, all the links will be 
proxied. Also, when you do add these URLs to the WAM table, I think you 
need to restart the terminal called "WeBridge Resolution Server" (along 
with the "WWW Server" and "Proxy Server" entries). I am not absolutely 
sure about that last part, but some of the links seemed to magically 
work after we restarted that terminal, so...

3) This should work for most targets that use CrossRef. However, every 
resource seems to have a different method of handling incoming DOIs, so 
you may need to adjust other entries in your WAM table. For example, we 
used to have the following WAM entry for Wiley: 
"*.interscience.wiley.com", which worked fine. But, as it turns out, you 
need to have *.wiley.com in order to maintained a proxied link. This is 
probably because Wiley uses another server (maybe 
www.wiley.com/something...) to "resolve" incoming DOIs.

I can't guarantee that the above will work for any resource or in every 
circumstance, as I haven't completed all of my testing yet. Still, so 
far so good...

Have a nice day,
