I’m trying to do file upload with rails and fcgi. Basically, i want my  
users to be able to upload images on the server.

After the upload, I get a 500 error from apache and in the error log I  
find this:

FastCGI: comm with server  
“/var/www/workspace/mydomain/public/dispatch.fcgi” aborted: error  
parsing headers: malformed header  
‘R0lGODlh9AH0AfcAAGA5YEAmQCATIP+Z/++P79+G3898z69pr49Wj4BNgHBD’

The images are uploaded and saved successfully. The problem seems to  
happen when the upload is completed. I’ve looked all over the web and  
didnt find anything.

I’m using …

Apache 1.3  
Rails 1.0  
mod\_fcgi 2.4.2

Any help is appreciated, thanks

Random idea that I accidentally hit:

Are you doing any puts calls to stdout? That works ok in webrick, but  
not under fastcgi.
