How To Cache/proxy Streaming Content - More Details Inside
Jun 4, 2008
I've got a dedicated server running my portal. Now we plan to soon launch broadcasting, where we via a webcam + microphone will broadcast (streaming WMV media) to all our members. Our members will then be able to interact with the speakers via chatting.
Now we are currently undergoing loadtesting, with our current setup, which is:
2. home PC with static IP and 1 MBit upload=>Video+Audio Streaming
So the member requests a page from the dedicated server, which has a chat window and a windows media player. The player will retrieve the video/audio content from the home PC. This is done by the client.
Now is pretty logical to see that there will be limitations in how many connections the home pc will be able to handle.
The question is: How do i make the dedicated server get the content from the home pc (so it only serves one connection) and then get all the clients to get their video content from the dedicated server ?
I've looked into the proxy modules for the apache server, however they (forward/reverse proxy) both passes the connection on to the remote machine and thereby not doing what I want to do.
I have a site where our budget is very constrained, and we're maxing out our unmetered pipe. The majority of the bandwidth is taken up by an active forum.
I offloaded most of the static content (images, .js, .css files) to a CDN (SimpleCDN) which I've been pretty happy with, the costs are very reasonable and fit within our limited budget.
They offered a service where if the content was not found on their network, it would check on our server for the file, retrieve it, and then serve it up from then on. Which was perfect for us as it allows us to use the CDN to serve image files uploaded by users in such a way that it's transparent to the end user.
However they're discontinuing this service, and though they're offering a similar service (based on rsync), they're charging $150 setup fee! So basically I have to pay $150 to keep using the service I've been using for a while. Which I can't really do.
So I'm trying to think of alternatives. I don't think I really need a full bore CDN, while we do have users from around the world, it's not a business site so a few ms isn't going to be the end of the world.
I just need a file hosting solution that has decent performance and fairly inexpensive bandwidth.
It's only 100-200GB / month maybe. At SimpleCDN that was only costing $8 / month.
I looked at Amazon, but they charge 1 cent for 10,000 requests which for us adds up very fast.
I'd almost think of just signing up for a Dreamhost account, but I would think using them to host just our images probably goes against their ToS.
I made changes in httpd.conf to redirect website to another website; after 15min I removed redirect but until now when client request website they are redirecting. I'm sure I remove redirect.
we are locating in UAE, UAE has transparent proxy for all Internet connections so I think the problem in proxy cache, How i can confirm it? then can I avoid it ?
also when I put dot "." at the end of link site working without redirect otherwise it's not working.
I'm assuming a corporate proxy cache is what they have set up. I have a client and every time I send them changes to a temporary page I'm hosting for review they can't see it.
They can hit refresh over and over but never see the new updates unless I change the name of the folder its in.
This is very annoying and it only happens with them and one other corporate client i have. They check on multiple computers and it will never refresh and load the new changes. I think this is their network cache that their IT dept. set up.
How can I get around this? I tried an htaccess trick I looked up for expiring files but it didnt work.
These files are on a shared hosting of mine on an Apache server.
Loading a page with ~150 files (most images and js files) i keep runing into "locked requests" that are not comeing back and block the whole page from finishing loading. The files differ every time.
I see this warnings in my error.log (looks like they are connected to the behauviour above).
Code:
[Tue Nov 19 20:38:10.890013 2013] [cache_disk:warn] [pid 216692:tid 15924] (OS 5)Access is denied. : [client x.x.x.x:58963] AH00699: rename tempfile to file failed: C:/temp/cache/aptmpcBQArf -> C:/temp/cache/H8Cta/9ha4U/Uhhhs/OlQfU/1Q.data,
I am using a Windows 7 and the proxy server is working fine. However, I need to run a web content filtering on the server. This should be able to replace or change specific words or phrases from an incoming html and deliver it to the client. I have searched the internet for days for a working configuration but none of them worked. Here is the current configuration I added on the httpd.conf file:
I am a non-tech person trying to configure Nginx to serve static content (apache will remain on port 80 for the dynamic stuff).
Nginx is already installed, what I need is a workable configuration file for nginx so that it serves all static stuff (images and a few folders with static html) and instructions in how to create it. The server is running DirectAdmin panel, Apache 2.24, PHP 5.23 and XCache 1.2.
I use apache with CentOS VPS hosting for my blog. I only host one blog in this VPS account. I have 1.5GB RAM and I have 7, 500 page preview per day. My page loading time is 2-3 seconds (according to the pingdom tool).
I want to know what is the best performance (faster web page loading) W3 Total cache option for VPS hosting blog. Currently I use Disk to enhance for page cache and database cache for disk.
In httpd-status i see that some IPs hardly sending POST command to index.php but can i somehow find out what exactly they are trying to post and into which form on that page ?
I bought domain name and web hosting from a company. Now the problem is that the company from which I booked domain and hosting doesn't exist.
Initially the hosting company sent me only FTP and mail server details. Now I need the cPanel details to configure database. So kindly request all of you to suggest me some solutions through which I can get the cPanel details.
But I want to know further, like I am having a vbulletin forum, usually it just shows task name php, can I use top command or any other command/tool to list which page is being processing? like, Code: PID USERNAME THR PRI NICE SIZE RES STATE TIME CPU COMMAND 28516 wnl 1 3 0 10M 7080K sleep 0:52 4.28% /root/home/forums/showthread.php?t=1234

Server load and Disk /dev/md3 (/home) are showing red dots.
to understand this page on cPanel. I can imagine that red dots are not a good thing while the green ones are, but I don't know what it all means or if I should be complaining about this to my host...
I have this nice vps, but its on linux, and I always wanted to run windows apps on the vps, because of the nice configuration. I already tried wine, but most of my windows apps don't work, cuz they require .net framework to run.
I tried to instal vmware server and virtualbox, but both of them complain about a kernel problem, they are unable to locate my kernel source, so they can't run.
I am linux newbie, and i am running on a centos 5 operating system.
Some people say its impossible to run virtualization 'inside' virtualization, but i already read some people that say its possible.

I've been using Clearancerack for about 4 or 5 months now and feel I should write an honest review about them considering there really doesn't seem to be too many.
Ever since the start several months ago, I've had nothing but a pleasant experience working with Chris and clearancerack.
So, here we go they get a :
Setup: 10/10
The setup is stellar. The first server I ordered was up the night that I ordered it (only a few hours) all ready to go. The servers even come with a free apc remote reboot port!
Pricing: 10/10
You could not ask for more affordable pricing than that of ClearanceRack, considering the extraordinary support, network, and all around company. Their prices are cheaper than those of the highest quality competitors, yet provide even higher quality service!
Even collocation pricing is very affordable! I will probably be sending up a few nodes in the next several months.
Network: 10/10
There has not been one second of downtime in the month's that I've been there. There was an issue with the network routing once, using bandwidth suppliers that the DC has connections to, yet Clearancerack does not use. This was fixed within several hours as well.
The network consists of a BGP mix of Peer1, All Stream, Shaw Big Pipe, MCI and peering to TorIX.
Almost all of my users experience faster downloads around the globe on the ClearanceRack network, than several of the other networks we've used throughout the US.
Support: 11/10 - Yes 11...
The support is stellar. They provide 24/7 E-mail (it really is 24/7) and REAL HUMAN Phone support (you won't get the usual leave a message, unless they really are busy and cannot take your call). At any time of day you email them, you'll have a response within minutes, even sales!
We've had one issue with one of our nodes in which Chris had to go into the datacenter to take a quick look. The issue was resolved in 30 minutes at the most.
Any requests we've made, whether it be licensing, IP allocations have all been handled extremely quickly, no matter what time of day it is.
Company:
Many times you'll hear people say, "They're great for a small scale company." Meaning, they're decent, but do have their downs that the higher scale competitors don't. Its not like that at Clearancerack. Every single thing about them is stellar, and the service is MUCH better than service I've received at various considered "higher scale and known" datacenters around the globe.
Clearancerack, ran by Chris - is ran by REAL people, wanting to make a REAL difference in the hosting market, and he/they are doing an amazing job at that.
You don't experience any poor customer service that you'll experience elsewhere. They are 100% honest with any sort of question, issue, or comment you may have. You WON'T get any of the lies, or uninformative information you receive elsewhere when an issue arises.
Personal:
Chris, I will continue to be working with you for many years to come, as I hope many of the current subscribers, and the future do to. Someone like you deserves the very best, and should GREATLY succeed in their business career. - Thank you for everything Chris! - You really know what hosting is all about.
Thats It!
Thanks for taking the time to read this review.
Generally you won't find a honest review with the ratings that I've given these guys, but THEY do deserve it, at the very least. I do not have one complaint about them as I do many other providers, and I've tried many throughout the globe.
I hope you will go ahead and try ClearanceRack for your dedicated solutions needs. They have no contracts, so you can sign up for one month, test out the service and make a final decision (although I can pretty much guarantee you will stay!)
Hostingcon:
If your going to hostingcon, check em' out! They have their own booth there!
I need several Windows VMs to test out some softwares and I plan on using virtualization technology to cut some costs.
I have a Linux(Debian Etch) dedicated server sitting to accomplish this. Specs are Quad Core Xeon 2.13Ghz with 4GB Ram/500GB HDD.
Now if I were to choose between Xen 3.1 and VMWare Server for the virtualization technology which would provide better performance?
I tried Windows on Xen 3.1 with PV Drivers and it seemed some what slow, but I'm not sure what the case was there so I can't say which would provide better performance overall.
There is serious clock skew all across the 4 CTs I have put in an OpenVZ HN which runs Debian GNU/Linux, the kernel Linux is v2.6.26, waldi tree. The HN shows correct time, the CMOS RTC is bang correct.
I have a PIX501 firewall with a wireless network attached to the outside interface and our local network attached to the inside interface.
I've setup access lists to permit the wireless clients attached to the outside interface to be able to access services on our inside interfaces.
The wireless clients are on a totally seperate /24 subnet.
Now everything seems to work fine with nat statements for our local wired subnets for example wirelessClients accessing the email server etc however the wireless clients cannot access the internet.
For the wireless clients to get out onto our internet connection they have to take the following path
So my question is how should I go about giving the access for the WirelessClients to be able to open web pages on the internet? For that to happen the traffic has to pass through the outside interface on the 501 firewall out of the inside interface onto the local switch and then back out of our main PIX515E to reach the destionation.
I'm fairly sure I'd need to modify the WebAccessNetwork access-list to permit WirelessLan to any against the port listings so thats not a problem I can change that how I'm not entirely sure I to go about it with the NAT statements.
I have a proxy site which is hosted with a proxy host, do i have to use proxy hosting as i have an account with another host i might want to use. The proxy hosting has run out.
