Dear list,

i’m having an issue with cached fastcgi responses with content length 0:

#curl [http://127.0.0.1/lq/aac/iPhone/a3efe0a282dafd](http://127.0.0.1/lq/aac/iPhone/a3efe0a282dafd)  
curl: (18) transfer closed with outstanding read data remaining

#curl -I [http://127.0.0.1/lq/aac/iPhone/a3efe0a282dafd](http://127.0.0.1/lq/aac/iPhone/a3efe0a282dafd)  
HTTP/1.1 302 Moved Temporarily  
Server: nginx/0.8.49  
Date: Thu, 26 Aug 2010 12:27:23 GMT  
Content-Type: audio/aacp  
Connection: close  
Location: [http://xxxxx/stream\_basis\_aac\_lq#4p765no3|0|0|vCubar|nnp|yd](http://xxxxx/stream_basis_aac_lq#4p765no3%7C0%7C0%7CvCubar%7Cnnp%7Cyd)  
X-CACHE: HIT

I understand the Content-Length Header is missing and therefor chunked  
transfer encoding breaks.

This only happens with cached responses and only with fastcgi\_cache.

Everything works fine, if i either disable fastcgi\_cache or if i wrap  
another nginx around my nginx+php-fpm setup with proxy\_cache.

i’ve done quite a bit of research but didn’t find any other solution  
than setting chunked\_transfer\_encoding to off, which effects every  
request.

i’m using nginx/0.8.49 with php-fpm 5.3.3 on gentoo

Is there any other way to fix this? Any thoughts are appreciated.

cheers

fastcgi\_param CONTENT-LENGTH $content\_length;
