Hi all, I deployed a Rails application on a Windows Server 2003 machine as follows: + I created two instances of Mongrel at ports 4001, 4002 to serve the application + I set up an Apache instance at port 8080 for balancing load for the two Mongrels => So I can access my website at URL http://mywebsite:8080/ + I want to allow users access my website without typing port 8080 in the URL. However, the server already runs IIS for several other web-sites at default port 80. Therefore, I used ISAPI Rewrite to forward requests from IIS (at port 80) to the Apache (and therefore towards the Mongrels) => I can access the website at URL http://mywebsite/ (To do these steps, I followed the guide in book Deploying Rails Application - Pragmatic Bookshelf) Everything seems to work fine until I find out the following problem: In my application, the user register form page allows user to upload his/her avatar. But whenever the file size is bigger than ~30KB, the browser keeps waiting for response from the server until getting timeout error. This error also occurs in any submitting form with a little big posted data. * Looking at the Apache error log file, I got the following error: ------------------ [error] proxy: pass request body failed to 127.0.0.1:4001 ------------------ => Apache seems to fail to forward request to Mongrel instance * Looking at the Mongrel log file, I got the following error: ------------------ Error reading HTTP body: #<RuntimeError: Socket read returned insufficient data ------------------ => Mongrel seems not to receive fully the data whose length specified in Content-Length attribute in the request header. One special thing is that this error just happens when I access the web-site via IIS, i.e., http://mywebsite. This does not happen when I try directly with Apache at http://mywebsite:8080 or Mongrel at http://mywebsite:4001/(4002) So I think there may be something wrong at the point of forwarding requests from IIS to Apache using ISAPI Rewrite, maybe related to max request length or something. But I totally get stuck at that so far. Please help if you have any suggestion to solve this problem. Thank you! Best regards, .Viet Trung.
