Rails - Sep 2006 - To render or redirect

Hi guys,

I have been using this code for a while and on the whole it works well.

# Display the search page
 def search
   @breadcrumb_title = ''Search''
   if request.get?
     @home_search = HomeSearch.new
   else request.post?
     @home_search = HomeSearch.new(params[:home_search])
     @search_conditions = Home.search_homes(params).to_sql
     if @home_search.valid?
       @homes = Home.find(:all, :conditions=> (@search_conditions))
       if @homes.empty?
         flash_message ''Your search has returned no results. Please 
revise your search critera.''
         render :action => ''search''
       else
         @record_count = Home.count(@search_conditions)
         render :action => ''search_results''
       end
     else
       render :action => ''search''
    end
   end
 end


There is just one little problem that my users are complaining about. 
They fill in the search form and hit enter and hey presto the results 
are displayed.  The only problem is that if they hit the browser back 
button, it returns to an empty search screen.  What I need to do is go 
back to the search screen containing the information they have already 
entered, so that they can alter.

I think my problem is I use render rather than redirect_to.  I have been 
trying to use redirect_to and trying to pass in the @homes variable, but 
no dice.  I have no doubt missed something blinding obvious.  Any ideas?

Thanks in advance for any help
Harvey
