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 ?

You may also check the syntax of the vhosts with -S

maybe you have to change the encoding using mod_proxy_html ProxyHTMLCharsetOut

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>


No change :\

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.

There is see KeepAlive=On

That is not what I meant. In the global Server config disable KeepAlive[1]
