Forum: Typo Blog defaulting to rss feed

Hey all,

All of a sudden my blog seems to be defaulting to an rss feed inside of
firefox.

It's at http://blog.michaelcdever.com and I checked it in Firefox 2 & 3,
both with the same result. It was working just fine last night. If I run
dispatch.fcgi it outputs the html for the blog as I would expect.

Anyone have any ideas??

It seems to be working ok now. I'm assuming you switchted to
dispatch.fcgi for now?

Can you check the contents of the file index.html in the public/
subdirectory of your typo installation? Is it RSS or html?

Hello,

It seems to happen sometimes on Rails app using caches_page and
serving both html and xml.
I have not found a workaround yet.

Yep, seems to be sorted. Thats a strange bug. I wonder why that happens, 
is
it just Typo, or do you know of it occurring with other rails apps?

I found this page:

    http://railsenvy.com/2007/2/28/rails-caching-tutorial

which says:

    Yup, page caching is going to ignore all additional parameters on 
your url.

So it should be a problem with all rails apps.

So my guess is that this happens whenever a URL like

   http://your.blog.org/?format=rss

(which caches like index.html!) is accessed before

   http://your.blog.org/

gets a chance to cache its version. I don't really see a solution for 
this: Is
there a way to make Rails ignore parameters supplied this way?

Or is there a way to set a low lifetime on anthing thAt is a feed?
Like maybe a minute? The problem would still be there, but reduced.

Hello,

Because of some other issues, I've planning to rewrite our cache
system from scratch. It will take some time and I'm not sure I'll be
able to do it before the next release, but it may also solve the HTML
VS XML issue.

Cheers,
Frédéric

I don't believe there is any lifetime option for the Rails page caching 
feature
that Typo uses.

However ...

... I have come up with a solution for this quandary! It is possible to 
add a
condition to Rails' page caching. I have just implemented the condition 
that the
query string must be empty. This means that *after a cache sweep*,

   http://your.blog.org/?format=rss

will return the RSS feed but will not cache anything. Then,

  http://your.blog.org/

will return the proper html and cache it. Then

  http://your.blog.org/?format=rss

will return the html. This is not what the client requested, but they 
shouldn't
be accessing the rss feed like that anyway, so I consider this a minor 
problem,
and certainly a lot less bad than the current situation.

I've committed the fix to typo's master branch.

Shouldn't this be http://your.blog.org/index.rss

That would be the one you _want_ people to access, and it should be 
cached. The
problem is that there is no way to stop people from accessing the first 
one and
messing up the cache.

An even worse example:

  http://your.blog.org/?year=1800

Guess what's in your cache now :-).
