We've tried numerous times sending update PUT requests to our Rails server and we keep receiving a 404 "The page you were looking for does not exist" Our update method is very simple (practically generic rails). def update @user = User.find(params[:id]) respond_to do |format| if @user.update_attributes(params[:user]) format.html { redirect_to @user, notice: 'User was successfully updated.' } format.json { head :no_content } else format.html { render action: "edit" } format.json { render json: @user.errors, status: :unprocessable_entity } end end end When I run CURL from the command line to

I am having a problem with a network request that should timeout, but the method is not called. The request is as follows: #define kCONNECT_TIMEOUT 20.0 request = [NSMutableURLRequest requestWithURL: aUrl]; [request setHTTPMethod: @"POST"]; postData = [jsonData dataUsingEncoding:NSASCIIStringEncoding]; [request setHTTPBody:postData]; [request setValue:@"text/xml" forHTTPHeaderField:@"Accept"]; [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; [request setCachePolicy:NSURLCacheStorageAllowed]; [request setTimeoutInterval:kCONNECT_TIMEOUT]; self.connection =
