RSS feedBy default in the Frog Blogging program, the URLs of the link to RSS feeds include a port number. Because this server goes thru a reverse-proxy server, the following correction is made to remove the port number from the URLs. Edit feedinfo.y at /var/local/Snakelets-1.44/webapps/frog/docroot, to replace a line with feedURL as follows:
feedBase=self.Request.getBaseURL()
if feedBase.count(':') > 1:
a = feedBase.rfind(':')
feedBase = feedBase[:a])
feedURL=feedBase+url("feeds/%s/feed.rss" % self.escape(user.userid))
Did the same to snakelets.py at /var/local/Snakelets-1.44/webapps/frog/frog, i.e., in def rss, edited as
feedBase = request.getBaseURL()
if feedBase.count(':') > 1:
a=feedBase.rfind(':')
feedBase=feedBase[:a]
rss=RSSFeed(blogtitle,
feedBase+frog.util.userURLprefix_snakelet(self, user.userid),
blogdescription, "Copyright by "+user.name, timetolive)
Pretty ad hoc, but let it work this way for a while... Hmmm, found it still doesn't work properly 
Now, really ad-hoc
Did:
def getServerName(self):
if not self.virtualhostport or self.virtualhostport == 80:
return self.virtualhost
else:
# return '%s:%d' % (self.virtualhost, self.virtualhostport)
return '%s' % self.virtualhost
on server.py at /var/local/Snakelets-1.44/snakeserver. OK, it's just an ugly hack, but it worked
Got RSS working properly
