A couple of weeks ago I got a bug filed against me in RSS Bandit with the title Weak duplicate feed detection that had the following description
I already subscribed to "http://feeds.haacked.com/haacked" feed. Then while browsing the feed's homepage the feed autodetection gets refreshed with a "new feed found", url: "http://feeds.haacked.com/haacked/". It is not detected as a duplicate (ends with backslash) there and also not detected in the subscription wizard.
Even though I argued that there were lots of URLs that seem equivalent to end users that aren't according to the specs I decided to go ahead and fix the two common types of equivalence that trip up end users
Within a few hours of shipping this in version 1.6.0.2 of RSS Bandit, the bug reports have started coming in hard. There's a thread in our forums with the title URL Corruption After Adding a Feed with the following complaints
After I add the feed at: http://www.simple-talk.com/feed/
I get an error in the Error Log and when I restart RSS Bandit, the URL has been truncated to http://www.simple-talk.com
Possibly related problem:
When I add "http://www.amazonsellercommunity.com/forums/rss/rssmessages.jspa?forumID=22" then RSS Bandit slices and dices it into "http://amazonsellercommunity.com/forums/rss/rssmessages.jspa?forumID=22".
Sorry about the period outside the quotation mark. I wanted to make sure the URL was clear.
Same problem--have a feed, I've used it in the past with RSSBandit and was trying to enter it (tried the usual way first, then turned off autodiscover, then tried to change it via properties) but no matter what I do the www. in front disappears, and the feed doesn't work. http://www.antipope.org/charlie/blog-static/
Each of these is an example where the URL works when the domain is starts with "www" but doesn't if you take it out. This is definitely a case of from bad to worse. We went from the minor irritation of duplicate feeds not being detected when you subscribe to the same feed twice to users being unable to access certain feeds at all.
My apologies to everyone affected by this problem. I will be dialing back the canonicalization process to only treat trailing slashes as equivalent. Expect the installer to be refreshed within the next hour or so.
