A web server refers to the software that helps to deliver web content that can be accessed either through the Internet or through an intranet. The primary function of a web server is to store, process and deliver web pages to clients. The communication between client and server takes place using the Hypertext Transfer Protocol (HTTP). The most common use of web servers is to host websites, but there are other uses such as gaming, data storage, running enterprise applications, handling email, FTP, etc.

I have  sun server that runs a local application that uses the following ports: JMS 5630, XML 9672,
ASP Http 80 and ASP https 443, i can only telnet to port 80, telneting to the other ports I get
unable to connect to remote host: connection refused. I checked the /etc/services and I do not see the ports listed.
BTW: This application used to work without problems...

I am having little difficulty in resolving one URL redirection in remote location. Example: My website is https://temp.company.local/dev/rel and it's accessible through Remote host. However, when user requests for https://temp.company.local, he is getting redirected to Apache manager page which I don't want. Can you please provide a solution to fix this problem so that only proper URL will work and half will not redirect to tomcat manager page?
Just to update I'm not using IIS.

Best Regards,
Short question that requires a lengthy answer....   For security reasons -- Should we host our website on a linux box or Windows?    Ultimately it will have to share data with our MS SQL server.   Also looking for someone reasonably priced but excellent web developer.... (do those go hand-in-hand?)

why do we use pluginmerge.sh  in websphere application server and when &how to use it?
I have 1 website with 1 IP in IIS using both port 80 and port 443. I own 2 wild card certs, one for the external address (@mycompany.com) and one of the internal address (@inside.mycompany.com)

Current SSL certificate that's tied to port 443 is using the external Cert. And the website is reachable external via SSL without issues.
Internally we can reach the website using http on port 80 with the FQDN and that works fine

Management wants SSL applied to the internal web site instead of using http. One method I thought of was to add an additional IP to the website. In Local DNS add a new host name pointed to that IP. Bind the internal Cert to the IP on Port 443. Everyone goes to the website using the new FQDN. To get to the internal Site they using the new FQDN. The concern I have with this approach is that the server still has 2 IP's and local DNS will reflect that. If anything anywhere references the FQDN of the server they could end up getting an error or the wrong item displayed. I

what other options are there?
I do NOT want my users redirected to mobile.htm, but just left alone regardless of browser.  On a smart phone even when they type out index.htm, they still get redirected to a broken link.  I am on tomcat nix server.
I have 2 domains. Domain A and Domain B.
Domain A has 2 websites on single server.
Domain A is going away and the web sites will be moved to a server in Domain B.

Problem is, that web master does not have time to reconfigure all the domain information in the existing code & config files to reflect the new server names. The systems cannot go down for the time being. Will something like this work?

  • transfer the Domain A's DNS zone information over to Domain B - this way the A.com domain record still exists
  • Going into the newly transfer DNS records and change the IP of the 2 website to point their new IP's in the B domain

anyone typing Server1.A.com in a browser will get resolution from the DNS server in Domain B which will then return the IP of the new website in Domain B.
Hi Experts,

We have a NLB cluster of three web servers in an environment of three nodes in a Hyper-V cluster with a shared SAN storage. The website URL points to the NLB cluster IP address. When we use Move/Live Migrate to move the web server(s) to a different node, the web site becomes down.

At the same time, each individual of the three web servers are just fine -- all three servers are up and running, and all are pingable. And if logging into each individual server and trying to access the website using URL from there, the website is accessible. Apparently the website only becomes down while accessing via NLB upon the Life Migrate of the server(s) to a different node occurs.

It is frustrating and mysterious. Do you know what could be wrong?

Hello Experts,
Hi, anyone explain me how to do 301 redirect in tomcat server, my problem is i have a index.html file in root folder of tomcat server, where this index.html file is forwarded to another folder root/xx/ui/ folder where my original index.html file is present, so now i want to 301 redirect the root insex.html to ui/index.html file. Please anyone help me.
I have set up an Nginx server serving a web application on the same server. I want to forward request like www.mydomain.com/myaccount to a local folder "/usr/share/nginx/html/app" There is a test index.html file under this folder.

I have the nginx.conf file setup like below.

                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

  • Main site A
  • Remote site B
  • Point to point connection between Main and Remote site
  • A & B in same same domain
  • we have internal DNS and External DNS servers
  • Internal DNS is within our domain, internal domain: local.web.com
  • External DNS is with 3rd party DNS providers, our domain: web.com
  • External Public IP nat'ed at firewall to internal IP of website IP.
  • External DNS name mapped to public IP

within our network we can load the website using the Internal URL address. However, resolution of external url is not working, failing with:
HTTP Error 404. The requested resource is not found
. If i were to load the external URL on my cell phone or with an external connection the site loads up with no issue.

I can't figure out why the external URL is failing to resolve within our network. Both internal and external URLS are different.

The only thing I can think of is that i may need to have an conditional forwarder but that makes no sense since I can resolve other external addresses.

I have a windows 2003 server running iis 6.  We have a website hosted on it (www.mydomain.org).  I'd like www.mydomain.org/folder to be redirected to an external website.  What would be the best way to accomplish this task?
For my needs......
I need to access the apps with an android tablet,
I need to run a legacy app Windows Write as well
I need to run an ERP app (Windows 7, M2M)
Please help me sort through the different offerings.
 These are what I am aware of:
Microsoft APP-V
Citrix Xen App
VmWare Horizon

Acronis protects the complete Microsoft technology stack: Windows Server, Windows PC, laptop and Surface data; Microsoft business applications; Microsoft Hyper-V; Azure VMs; Microsoft Windows Server 2016; Microsoft Exchange 2016 and SQL Server 2016.

I have an app that uses a service. I need to test the app from within our domain and over the internet. The customer has both the production service and the a new test version of the service running on the same server. What i'd like to do is set up a dns zone that resolves to a different IP address based on whether its being requested from the domain or over the internet. From here I can set up the web servers (IIS) site bindings to redirect the request based on the IP address to either the production or test service. How can I configure this in the Windows Server DNS Manager?
Hi Experts,

Hopefully you can help with a very bizarre issue
We noticed an issue with what we originally thought was the fault of our load balancers, where the site would go down, and be marked down by the LB, but when you attempt to browse directly to the server itself, the page would return.

A bit of investigation later, it appears to be a local problem on the web servers itself. Monitoring using wireshark, we could see the LB making the a health check (using a GET request to the URL), and the server delaying its response for an extended time, causing the health check to fail.

However, new requests coming from other IP's the web server responded to immediately

Does anyone know why this may occur?

The servers in question are Windows 2016 x64
