I don’t know what is root of the problem that I have, probably somebody
could answer the question.
I have extremely simple rhtm file. See below
\<% if (a.id [http://a.id](http://a.id)) { %\>
\> **\<%= link\_to("Download", :controller =\> "attachment", :action =\> "download", :id =\> a.id ) %\> \<% } %\>**
**And when I try to view the results of this rhtml Webrick hangs up. CPU
usage
100%. However Apache fcgi works fine for this template.
If I remove if {} condition then everything works fine. What is the
problem?? WebRick bug??**
**My environment: WinXP, ruby 1.8.2-14, rails 0.14.2**

don’t you want this instead:
\<% if a.id %\>
…
\<% end %\>
What you have looks more like C.
