trouble on redirect_to's

djsodom · Sep 11, 2006

I've narrowed down the problem I've been having with litespeed to methods where I am using redirect_to. For example, something like:

def create
@workbook.track_results(params[:answer_id])
if @workbook.total == @workbook.items.size
redirect_to history_url(@workbook.game)
else
redirect_to quiz_url(@workbook.items[@workbook.total])
end
end

Maybe 50% of the time with litespeed the redirects die and nothing happens. For example, there is no response listed in firebug. I have no problem with webrick or lightty.

Any ideas what this could be?

Here is an output from my rails development log:

Code:

Maybe the redirect URL is mis-formated under LiteSpeed LSAPI, there are subtle differences in request paramters that Rails received between LiteSpeed LSAPI and webrick.
Run the app under Litespeed and dump the URL.

djsodom · Sep 12, 2006

Perhaps. My redirect URL is a little unconventional:
http://localhost/quizzes/index/sports?tid=7&curator_id=1

..where "sports" is a non-numeric id.

When you say dump the URL, how do you mean?

mistwang · Sep 12, 2006

"Dump the URL" means that write the URL to the log file or somewhere.
I need to get an idea about how the URL looks like, and it will be even better if you can log the whole redirect response sent back to LSWS by Rails.

Thanks George. I will work on this and get you some info. I put it aside for awhile to work on something else.

Okay, I used livehttpheaders to dump the URLs using both Litespeed and Lighttpd for contrast.

I've attached both text files it generated (though I deleted some of the calls to my stylesheets for example for brevity).

What I'm doing is basically an ajax quiz.

A question is presented. the user clicks on a question, which posts the data to the db, and is then redirected to another question that renders as a partial replacing the html of the previous question.

i can't seem to get the text files to actually attach to this message, so I'll just post the text here:

The log shows that the request for "/quizzes/12" failed when LSWS is used. Only get "200 OK ..." line, other header lines are missing.

You can try this request directly, without redirection, redirection is working fine.

Take a look at how this request being handled by rails, and anything special makes LSWS fail then I can fix it.

You can use comnand "lynx -mime_header http://localhost:82/quizzes/12" to dump the whole response, wget can do it as well, I forgot the command line parameter.

Please give http://www.litespeedtech.com/packages/lsapi/ruby-lsapi-1.9.tar.gz a try, your problem might be fixed already.
