I am hosting a couple of web sites on couple Linux boxes and OWA on a Windows box in my office. Currently http is forwarded to Host_W and https is forwarded to Host_M.  Host_W serves pages for www.site-m.biz, www.site-d.net, and www.site-f.com while it forwards requests for host_l.site-s.org and www.site-s.org to Host_L. The current structure looks like this:
 
Current Config
What I want to do is forward both http and https to Host_W while serving the same three sites and forward https requests for mail.site-m.biz to Host_M and requests for site-s.org to Host_L. The structure would look something like:

Disired Config
 I have attached sanitized copies of what I think are the relevant config files.
 
The port forward is not a problem, simple change on the firewall. Installing Let's Encrypt certificate on both Nginx and Apache2 are heavily documented and a Godaddy certificate for mail.site-m.biz is already installed on Host-M.

What I don't have a handle on is the changes needed on the Apache2 on Host_W. I think it would be just to add something to the site-m.biz.conf like (and something similar to site-l.org.conf):

<VirtualHost *:443>
        ServerName mail.site-m.biz

        SSLEngine On
        SSLProxyEngine On
        ProxyRequests Off
        SSLProxyCheckPeerCN off
        SSLProxyCheckPeerName off
        SSLProxyCheckPeerExpire off
        SSLInsecureRenegotiation on
        SSLProxyVerify none
        SSLVerifyClient none

I have a relatively simple page that renders differently depending on whether the page is located on the web server or on the browsing system as a local file.  The HTML file being rendered is identical in both cases.  The problem appears to occur only in Firefox.  IE renders correctly for both situations.

While it is true that embedding styles in a link is not considered "best practice", the only links where this particular styling are desired are at the bottom of the page.

The server is Apache, and I have checked that the HTML being received (appears to be) the same as the HTML file on the host.

What is the issue causing this rendering difference?

I am having some problems. I switched over from one e-commerce system to another a while back and this changed the url structure of some of the pages. I was fine with this and set up some rewrite rules. Somehow this has stopped working and I am not sure why.

I need to change

  • /product/{Category-Name}/{URL} to /{URL}
  • /ecategory/{Category-ID}/{URL} to /{URL}
  • /manu/{URL} to /{URL}
  • /news/{category-name}/{URL} to /blog/{URL}

I am using

RewriteRule   ^/?(product|ecategory)/([^\/]+)/(.+?)\$  /$3  [R=301,L]
RewriteRule   ^/?(manu)/(.+?)\$  /$2  [R=301,L]
RewriteRule   ^/?(news)/([^\/]+)/(.+?)\$  /blog/$2/$3  [R=301,L]
RewriteRule   ^/?(newscategory)/([^\/]+)/(.+?)\$  /blog/$3  [R=301,L]
RewriteRule   ^/?([0-9]+)/(.+?)\$  /$2  [R=301,L]

But this is not working now and I don't have enough knowledge of htaccess redirects to work out what is wrong. I have been making changes and looking online but I feel like I am going in circles and this is very confusing.

Please, can anyone give me some advice?

Hi, I am running techgardens.com/optical-engineering.

My client is creating pages at techgardens.com/optical-engineering/ciena, techgardens.com/optical-engineering/Infinera, techgardens.com/optical-engineering/Coriant, techgardens.com/optical-engineering/BTI, techgardens.com/optical-engineering/JDSU.

She would like, when someone clicks on a link for one of those pages, that they see the page, but the url reads  techgardens.com/optical-engineering/.

I think I can do this with htaccess, but need some help. The WP htaccess already has this:

# BEGIN WordPress
AddHandler application/x-httpd-php70 .php
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /optical-engineering/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /optical-engineering/index.php [L]
</IfModule>

Can I alter that to read:

# BEGIN WordPress
AddHandler application/x-httpd-php70 .php
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /optical-engineering/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /optical-engineering/index.php [L]
RewriteRule ^ciena/?$ /
RewriteRule ^Infinera/?$ /
RewriteRule ^Coriant/?$ /
RewriteRule ^BTI/?$ /
RewriteRule ^JDSU/?$ /
</IfModule>

And will that give me the result we want? Thanks!

Hi Expert
I need to debug some issues related to redirect rules.

for example:
rewritecond  request_uri /xxx

so In the above condition I am passing request_uri . is their anyway to print or echo and capture request_uri incoming data .

this helps to capture values and analyse log.

I have an old website that runs on Neowebscript, which was an extended version of TCL for Apache.  Does anyone know any web hosts still hosting Neowebscript sites, or downloadable versions of Neowebscript that will run under an up to date version of Apache or IIS ?

when you use a 3rd party to host your website, where does the responsibility typically split in terms of the technology stack on who has to apply patches to all the relevant components of the web stack? e.g. do they typically patch your CMS and any underlying databases, or only lower levels of the stack?

Here is my configuration for protecting one of my directories using mod_authn_dbd...
<VirtualHost *:80>

DBDriver mysql

DBDParams host=127.0.0.1,port=3306,dbname=myDB,user=root,pass=*****

DBDMin  4
DBDKeep 8
DBDMax  20
DBDExptime 300

<Directory "/path/to/ProtectedDir">
AuthDBDUserPWQuery "SELECT encrypt(passwd) AS password FROM myTable WHERE user_name = %s AND DUE_DATE>=CURDATE()"
  AuthType Basic
 AuthName "CurrentIssue"
 Require valid-user
 AuthBasicProvider socache dbd
</Directory>


    ServerName www.mySite.com
    ServerAlias mySite.com
    DocumentRoot /Server/WebSites/mySite
    ErrorLog /Server/WebSites/mySite/error.log
    CustomLog /Server/WebSites/mySiterequests.log combined

<Directory "/Server/WebSites/mySite">
    AllowOverride None
    Require all granted
</Directory>

</VirtualHost>

Open in new window

My question is how do I protect another Directory using a different mysql DB?

I've tried adding 
DBDParams host=127.0.0.1,port=3306,[u]dbname2[/u]=myDB,user=root,pass=*****

Open in new window

and 
<Directory "/path/to/ProtectedDir2">
AuthDBDUserPWQuery "SELECT encrypt(passwd) AS password FROM myTable2 WHERE user_name = %s "
  AuthType Basic
 AuthName "Admin"
 Require valid-user
 AuthBasicProvider socache dbd
</Directory>

Open in new window

As expected this breaks both Directories.
Any ideas on how I would accomplish this?
Is there any way to use mod_authn_dbd with htaccess?

Dear Experts

We have hosted CRM application  on-premises which is web-based and every user has email settings to be configured, the email server is on internet and also other integration like SMS(sms service provider is on external network) and third party applications, all these were perfectly working until the recent changes at the gateway level and internal IT policy,  I suggested them may be the crm servers are not allowed to talk to the external network of email server and sms service providers,.
please find the attached error logs captured, and these the crm server is of windows server 2012R2 can you please help on how to test and confirm to them based on test result like the issue of connectivity, is it recommend to telnet from the web-application crm windows server to the destination email server/sms sever provider server with the ports -- is this the right way OR any other way to check and ensure the necessary ports and access at the gate way/firewall is opened or not, please suggest.

This is a follow on question to https://www.experts-exchange.com/questions/29115269/Why-Does-Mysql-Keep-Increasing-Memory-Usage.html

Now it appears that the memory leaks are coming from php-fpm and Apache.

Please tell me how to isolate what is using up the memory so quickly.

In less than an hour I have lost .9 GB.

Hi,

I have created a web project using PHP and c++. In brief what it does is connects to an remote Exchange server and gets the data from it. The website functions properly, but it requires some changes to be made to the PHP.ini file (enabling LDAP, COM, etc). I am using XAMPP.
The issue I'm facing is that the changes made to the php.ini file is not taking effect. I have created a c++ console application which runs in hidden mode and modifies the php.ini file. When I open and check the ini, the changes are there in it but when I run the website trough XAMPP it does not pick up the changes made to ini. I have tried restarting the Apache service, restarting XAMPP, restarting machine as well, nothing worked.

Though the problem is not concerning exchange server, any help would be greatly appreciated.
Thanks.
