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.

Hi all,

I am having a serious problem hosting websites based on Redhat or Centos on Hyper-V.  While on physical server that is not the case even when the CPU and memory is much less than what is been allocated for on Hyper-V.

30 - 50 user's try to access a page to upload document or login, the server gets hanged completely.  sometime we have to force restart because we cannot even login to reboot the server.  but that is not the case with physical server even when the memory and CPU is half of what is been used on Hyper-V.

One of the issues I am facing on Hyper-V is the memory releases, which keeps increasing and never get release unless I use a run /bin/sync; /bin/echo 3 > /proc/sys/vm/drop_caches on crontab to release the memory or force restart the server.

I am getting to a point to move all my web onto physical machine due to that problem.  can you please help me resolve that problem.  Is the fix from the Windows, Linux or Apache?

Free Tool: Subnet Calculator

The subnet calculator helps you design networks by taking an IP address and network mask and returning information such as network, broadcast address, and host range.

One of a set of tools we're offering as a way of saying thank you for being a part of the community.

I am trying to install multiple mediawiki farm sharing same resources (4 in total), exactly like Wikisource.org, on Amazon Web Services EC2. This installation will consist of the main wiki in English (wikiexample.org), two languages sub domains (lang1.wikiexample.org, lang2.wikiexample.org) and a commons hosting their media files (commons.wikiexample.org).

The wikis will have the extensions of Wikisource like ProofreadPage, PDF handler, Djvu extension and the Translate extension.

It should be possible to maintain and upgrade the entire wikis centrally and not one at a time.

Can anyone please put me through how to go about this?

Thank you.

Hi,

I have a site which runs https (f.e. https://onenote.microsoft.com) . I'd like to redirect http://mysite.mydomain.com to that site but keep the url http://mysite.mydomain.com 

Can that be done?

Two Windows domains
1domain local to our corporate office
2nd domain connected via VPN tunnel
No authentication / trusts between domains

Website site located in 2nd domain. This is an "internal" site and is not accessible outside of our network connection via VPN tunnel

We are unable to access site in 2nd domain unless we utilize IP address of the web server.

Should I be looking at DNS forward lookup zone? Should I be making changes to local user HOST file?

My server load averages are going way high and too many processes are being consumed. Is it a DDoS attack or something wrong with the server?

Hi there!

I've been trying to figure out how to copy all the tags from my instances to the attached volumes in a region.
I found two Lambda scripts which say they do that, but I can't figure out how to make use of them (I'm not a Lambda whiz)

#1
https://gist.github.com/mlapida/931c03cce1e9e43f147b

#2
https://gist.github.com/deepthawtz/8726d3d0efe4fb48d01180074fa818f9

When I create a function, each of those throws errors and never works. Can someone explain to me ELI5 how to make a function that will copy my instances tags to my volumes, ideally I'd run this scripts when I need it.

My instances are in us-west-2c

Source: https://www.mnot.net/cache_docs/#expires

They are saying:

Although the Expires header is useful, it has some limitations. First, because there’s a date involved, the clocks on the Web server and the cache must be synchronised; if they have a different idea of the time, the intended results won’t be achieved, and caches might wrongly consider stale content as fresh.

I see this in several places on the internet.

We know, this is valid for HTTP dates:

HTTP dates are always expressed in GMT, never in local time.

I'm wondering if HTTP dates really always depends on the clock / time of the Web server (the same applies to caches).

That would be only the case in the following situation. You have:

- time on server
- time zone of server

A server could calculate the Greenwich Mean Time by itself with "time on server" and "time zone of server". So in a case like that, the GMT date depends on the "local time".

So actually the question is: "Is a Web server calculating GMT time by using its local time?"

I would be a bit suprised if that's the case. The GMT / UTC date must be everywhere the same, so it would be weird if a server let it depend on the local time.

But if it's not like that, then this is not true in my opinion:

the clocks on the Web server and the cache must be synchronised

So how I have to see this exactly?

Hi

I have publicised in the local press a feature I am running which I have called Walk-In-Wednesdays.

So in the newspaper I put www/whatever/Walk-In-Wednesdays

I have realised a little late that this could be prone to errors of typing. ie for people for type walk-in-wednesdays or

walk-in-Wednesdays

So I wonder what is the best damage limitation for case sensitive errors.

I am using an old version of Dreamweaver to publish and the server is run on Linux.

Hi,

I hope that someone is able to help. The web development team have changed the current website that we are using. We have an order download application that integrated into mageno.

The issue is that I try to change the endpoint address to the following and I receive an error:

https://old.filofax.co.uk/index.php/api/v2_soap/index/?wsdl=1

Error message is attached(error1)

I have also tried to generate a proxy class using the same error message.

My issue is that I can browse to this URL ok.

I would appreciate any help. I have contacted the hosting company and they don't have any iea.

Best Regards,

Ross

i'm expecting to configure nginx to load balance the load among a changing bunch of backend servers and do not want to loose reactivity ( nor send a dns query per http connection ).

do you know how often the hostname is resolved ?
is this configurable ?


<side optional question>
do you know if this setup prevents cookie-based stickiness ( which i do not strictly require but would like to have if possible nevertheless ) ?
... actually i'm not even sure stickiness is even supported for fastcgi backends

the doc suggests each IP will be used in round-robin fashion. i'm assuming nginx grabs all the IPs in one query and does not rely on the dns itself to perform the round-robin.

i'm also interested if you know whether this can be weighted by specifying the same ip multiple times ( assuming the dns handles it )
</side>

thanks a lot for your help

please do not elaborate on how dangerous this is/might be or better setups or whatever different subject unless you know the answer to my question or possess helpful experience. i'm aware of alternatives, pros, cons...

i might be interested in alternative software providing they provide the above feature AND are event-driven or equally efficient. apache does not even come close (please do not debate). lighttpd only provides such a feature in an abandoned branch AFAIK. other less common fast implementations i know of usually do not do fastcgi.

I have a project assigned that I need to do performance load test.
The setup consists of one load balancer, 8 web servers, 1 SQL DB server, 1 File server and 1 video server
Users log in to Web based application using sql logins and they access resources such as files, videos.

I need to do performance testing for server loads in term of SQL connecitons, files and video access through web.
Let's say I would like to know how many maximum users file access/sql connections server can handle. (need to test for thousands of users access/connections to find out maximum)

Please advise how we can do above ? Is there any application that can do above ?

Many Thanks

We have a pfSense 2.3.4 with LAN, WAN, DMZ.
In DMZ subnet, we set up a Network Load Balancing cluster with two web servers in a 2012R2 Hyper-V environment. Their IP are:
DMZ port: 10.10.2.1
Server1:     10.10.2.21
Server2:     10.10.2.22
NLB Cluster: 10.10.2.100
NLB mode: multicast

Inside the DMZ subnet, each host can ping other hosts without a problem. The only stumbling block is, from pfSense, I can NOT ping the NLB cluster even I am able to ping all other servers in DMZ subnet. As the result, the cluster is useless.

In pfSense, I can see there is no ARP table entry for this cluster IP. How come?

I bet the Hyper-V NLB cluster is not new and am wondering if anyone ran into this issue before. Please help.

Hello,

I've been manually creating accounts in my WHM installation by using the functionality that's native to the program (i.e. I click create account, type in a domain, username, password, and select a package) to create an account for that user that has it's own cPanel installation.

I'm wondering if there's a way (either through software, api, or script) to do this in bulk? Any guidance someone can give would be greatly appreciated. If the answer is via script or api, I would appreciate any general direction you could give about how I actually would go about using it. Thanks in advance!

We are looking for a self-hosting alternative just like "WeTransfer"


If it could run on a linux server it would be great. (Windows Server is also OK)

We would like the service to be hosted at our servers, because there could be some critical data between.


The thought was :

Enter the URL
"Press here to upload a file"
Upload
Now it generates an unique URL, the costumer can send out via an email.


I Found this http://alternativeto.net/software/wetransfer/?platform=self-hosted
But would like to hear something you could have any experience with.

We are willing to pay for the software, but open source would be great too.

Hi guys,

I'm trying to utilize a PAC file hosted on one of our web servers to whitelist only specific websites.  The PAC file works, however, it's blocking some of the pages and not displaying the sites correctly.  Here's an example entry.

Function FindProxyForURL(url, host) {

if (shExpMatch(url, "*.happyclicks.net*")) return "DIRECT";
if (shExpMatch(url, "*.seussville.com*")) return "DIRECT";
if (shExpMatch(url, "*.picassohead.com*")) return "DIRECT";
if (shExpMatch(url, "*.pbskids.org*")) return "DIRECT";
if (shExpMatch(url, "*.mylanguages.org*")) return "DIRECT";
if (shExpMatch(url, "*.brainpop.com*")) return "DIRECT";

return "127.0.0.1";
 
}

Can anyone offer any assistance in allowing all the entire site through so this could function?

Thanks,

Nico
