 Posted: Tue 03 Mar '15 16:28 Post subject: Apache 2.4 stop loading ressources |
 |
|
Hello,
I encounter a strange issue with Apache.
My apache proxy is configured to work as a reverse proxy with virtuals hosts using SSL.
When I try to load a web site page with several ressources, internet navigator begin to load ressources but often stop without ending.
It continue to load (cursor) but don't do anything.
On both side (client and server), requests terminate with status 200 so all seem good but... (debug navigateur and acces.log OK)
After several F5 (refresh), all ressources are finally loaded and the html page display correctly.
Here is my configuration :
Server OS : Ubuntu server 14.04.2 (64 bits)
Apache version : 2.4.10
SSL version : 1.0.1f (ubuntu version)
-------------------------------------------------------------------------------
An example of host :
...
<VirtualHost 192.168.254.16:443>
ServerName ged.irsa.fr
SSLEngine on
SSLCertificateFile /etc/certificates/ged.irsa.fr.2.crt
SSLCertificateKeyFile /etc/certificates/ged.irsa.fr.2.key
SSLCertificateChainFile /etc/certificates/gandi/Gandi_bundle_CA.pem
SSLProxyEngine on
SSLProxyCACertificateFile /etc/certificates/ged.irsa.fr.2.crt
ProxyRequests Off
ProxyPreserveHost On
ProxyPass / ajp://192.168.254.5:8009/
ProxyPassReverse / ajp://192.168.254.5:8009/
</VirtualHost>
...
-------------------------------------------------------------------------------
Modified configuration in apache2.conf file :
...
AcceptFilter http none
AcceptFilter https none
EnableSendfile off
EnableMMAP off
...
-------------------------------------------------------------------------------
Modified configuration in mods_enabled/ssl.conf :
...
SSLCipherSuite ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-DSS-AES128-GCM-SHA256:kEDH+AESGCM:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA256:DHE-RSA-AES256-SHA256:DHE-DSS-AES256-SHA:DHE-RSA-AES256-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:AES:CAMELLIA:DES-CBC3-SHA:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK:!aECDH:!EDH-DSS-DES-CBC3-SHA:!EDH-RSA-DES-CBC3-SHA:!KRB5-DES-CBC3-SHA

I have test many things but nothing worked for the moment.
I can provide more details if necessary.
If you have any lead in order to resolve this problem, i will really appreciate it !! (It will save me !)
Thank you |

The IO errors are often because of a buggy backend.
You can try
| Code: |
SetEnv force-proxy-request-1.0 1
SetEnv proxy-nokeepalive 1
RequestHeader unset Expect early

Thank you for your reply.
I have added this conf in my apache2.conf file but it does not resolve the problem.
I've also desactivated the "keep alive" functionality which seems to slow down responses.
KeepAlive Off
But no real improvement so far.
I also do tests on linux OS and it seems to wrok "fine". Its slow but the page is fully loaded. |

| Yes KeepAlive increases the speed, since the browser can reuse a made connection. |
