 |
|
Good afternoon all,
I'm currently creating a brand new apache reverse proxy on apache 2.4.39 (the former one runs 2.2).
My config syntax is fine (double checked with -t), the proxy job is done by apache, the daemon is up and running, however I get "blank pages" displayed for some vhosts.
Troubleshooting actions :
Try to curl http(s)://theRemoteURL --> worked fine, so it's not due to ACLs
Checked apache's logs --> nothing related
When I display the web browser developper tools, I get this message :
net::ERR_INVALID_CHUNKED_ENCODING 200 (OK)
My server is running Solaris 11.4, and I have multiple vhosts configured.
Here's one of them :
| Code: | <VirtualHost *:80>
ProxyRequests off
ProxyPreserveHost on
ServerName MYSITE.TEST.COM
Redirect permanent / https://MYSITE.TEST.COM/
</VirtualHost>
<VirtualHost *:443>
ServerName MYSITE.TEST.COM
ProxyPreserveHost on
SSLEngine On
SSLProtocol ALL -SSLv2 -SSLv3
SSLCipherSuite ECDHE-RSA-AES256-SHA384:AES256-SHA256:!RC4:HIGH:!MD5:!aNULL:!EDH:!AESGCM;
SSLHonorCipherOrder on
Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains"
<Proxy *>
AddDefaultCharset Off
Require all granted
</Proxy>
<Location /phpmyadmin>
AddDefaultCharset Off
Require ip 1.2.3.4
Require ip 2.3.4.5
Require ip 3.4.5.6
</Location>
ProxyPass /PJ !
ProxyPass / http://THEWEBSERVER/
ErrorLog "/etc/opt/csw/apache2/logs/error_MYSITE.TEST.COM_443.log"
TransferLog "/etc/opt/csw/apache2/logs/access_MYSITE.TEST.COM.log"
CustomLog "|/usr/bin/logger -t apache -i -p local6.notice" combined
</VirtualHost> |
Any idea ? |

Thanks for the -S information, I didn't know about this one!
When I run httpd -S, I get a list of the vhosts, ordered by port, and no warning / error.
I get this in the bottom :
| Code: | ServerRoot: "/opt/csw"
Main DocumentRoot: "/var/opt/csw/apache2/htdocs"
Main ErrorLog: "/var/opt/csw/log/apache2/error_log"
Mutex ssl-stapling-refresh: using_defaults
Mutex rewrite-map: using_defaults
Mutex ssl-stapling: using_defaults
Mutex proxy: using_defaults
Mutex ssl-cache: using_defaults
Mutex default: dir="/etc/opt/csw/apache2/mutex" mechanism=default
Mutex watchdog-callback: using_defaults
Mutex proxy-balancer-shm: using_defaults
PidFile: "/var/run/httpd.pid"
Define: DUMP_VHOSTS
Define: DUMP_RUN_CFG
User: name="daemon" id=1
Group: name="daemon" id=12 |
In a vhost, I've added the charset directive like ( see line 4):
| Code: | <VirtualHost *:443>
ServerName MYSITE.TEST.COM
ProxyPreserveHost on
ProxyHTMLCharsetOut *
SSLEngine On
SSLProtocol ALL -SSLv2 -SSLv3
SSLCipherSuite ECDHE-RSA-AES256-SHA384:AES256-SHA256:!RC4:HIGH:!MD5:!aNULL:!EDH:!AESGCM;
SSLHonorCipherOrder on
Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains"
<Proxy *>
AddDefaultCharset Off
Require all granted
</Proxy>
<Location /phpmyadmin>
AddDefaultCharset Off
Require ip 1.2.3.4
Require ip 2.3.4.5
Require ip 3.4.5.6
</Location>
ProxyPass /PJ !
ProxyPass / http://THEWEBSERVER/
ErrorLog "/etc/opt/csw/apache2/logs/error_MYSITE.TEST.COM_443.log"
TransferLog "/etc/opt/csw/apache2/logs/access_MYSITE.TEST.COM.log"
CustomLog "|/usr/bin/logger -t apache -i -p local6.notice" combined
</VirtualHost>

| With the development tools, can you see any content that is passed by apache? |

James,
I found a dirty fix.
In my apache 2.4 httpd.conf file, if I add this :
| Code: | SetEnv downgrade-1.0 1
SetEnv force-response-1.0 1 |
then the pages are loaded normally
Before
After
It's clearly a dirty fix, but also an indication |

| Okay that is because of KeepAlive. Disabling that would do the trick. |
