So, I have an apache 2.2.16 (64 bit) installed on a Debian Server. I have configured a proxy, for a specific url to map to my backend Tomcat 7 server.
Everything works fine for all of the GET/POST requests except for multipart POST requests. The error log of apache is showing the followinf lines:
[error] [client CLIENT_IP] (20014)Internal error: proxy: error reading status line from remote server TOMCAT_IP:8081 [error] [client CLIENT_IP] proxy: Error reading from remote server returned by /svc/document
Strange thing is that POST multipart works fine if I upload a ZERO Kb file, but fails with other files (no more than a few bytes). And everything, including uploads works fine on my developing environment (XAMPP + mod_proxy + tomcat)
Tomcat 7 connector:
<Connector port="8081" protocol="HTTP/1.1" address="TOMCAT_IP" maxThreads="6000" connectionTimeout="40000" URIEncoding="UTF-8" maxPostSize="8388608" redirectPort="8443" />
Proxy is configured as follows:
<VirtualHost *:80> DocumentRoot /var/www/frontend/ ServerName frontend.com ProxyPass /svc/ http://[TOMCAT_IP]:8081/web/ connectiontimeout=40 timeout=60 Keepalive=On min=20 acquire=20 retry=1 </VirtualHost>
I even tried some suggestions, one by one and all in once, as found on similar question, but with no luck:
<VirtualHost *:80> DocumentRoot /var/www/frontend/ ServerName frontend.com ProxyPass /svc/ http://[TOMCAT_IP]:8081/web/ connectiontimeout=40 timeout=60 Keepalive=On min=20 acquire=20 retry=1 ProxyBadHeader Ignore ProxyRequests Off LimitRequestBody 8388608 SetEnv proxy-sendchunked 1 </VirtualHost>
I tried ProxyPassReverse, raise timeout, ProxyBadHeader Ignore, setenv proxy-initial-not-pooled 1 etc. nothing seems to work... Any idea?
