• ASP.Net Authentication with MVC2--how to integrate with DB?

  - by alchemical

  I'm trying to understand the authentication section sample project that opens in a new MVC2 project in VS2010. It essentially lets you register, login, etc. I looked through the code that implements this briefly, it looked fairly complicated. (10 tables, 40 sprocs, 10 views, 4 models, 1 model, 1 controller, etc.) Is it best to utilize this provided framework for authentication? If so, how would I integrate this with my own database models (which has user and role tables, etc.). Also, if I use their framework, are there any performance issues at higher traffic volumes (like SO for example), do I need to become responsible for maintaining the authentication DB as well in this case?

• What is the advantage of WSDualHttpBinding in WCF?

  - by schmoopy

  How much benefit would there be to using WSDualHttpBinding with IIS hosted service vs. a client poll that calls the WCF service, assuming in the latter the service cached the data in question? This scenerio would be for a notify type of service where the clients need to be notified by the service when an event occurs. Specifically, what advantages would WSDualHttpBinding provide over polling? ie: Less network traffic, faster to design, easier to maintain, more control ??? From what i understand, WSDualHttpBinding is less scalable than client polling, so why use it at all? Edit: As Matt supplied, time critical can be one reason for the duplex binding. Here is what i have so far: WSDualHttpBinding adv: can get immediate response w/o waiting on polling timer dis: less scalable than WsHttpBinding dis: less firewall friendly I'll add to this based on comments, please let me know if i state anything incorrectly. thanks for you input :-)

• Explain difference in SQLIO numbers for RAID 0 versus RAID 5 over 6 disks

  - by markn

  When using the SQLIO benchmark tool on a 4-core Dell server with 6 15k 450GB (fast) drives, RAID 0, we found the max throughput was 2MB per second. But when configured as RAID 5, we get 30 MB per second. It seems that the RAID controller, Dell Perc 5i integrated controller, is maxing out the throughput per disk. With RAID 5, I expect to get a bump due to stripping, but not a 15x difference. Like good programmers, we suspect the hardware , but we could be missing something. This is predominately write traffic.

• video file download issue

  - by George2

  Hello everyone, I am using VSTS 2008 + C# + .Net 3.5 + Silverlight 3.0 + ASP.Net to develop a Silverlight application (a video media player) in browser and the function is simple, just use MediaElement to play a remote video file. The remote server is Windows Server 2008 + IIS 7.0 + IIS Media Bit Rate Throttling Control. Since the request media URL can be discovered (e.g. from traffic sniffer), and I want to know how to prevent from download directly from the Url? i.e. I want end user to use my Silverlight media player application in browser to play the file, prevent them from download to local directly. Any easy and quick solution or reference code/documents? thanks in advance, George

• Accessing Squid Proxy over internet

  - by prateekdayal

  Hi, I recently finished installing Squid on a VPS I have in the US and its working fine locally (I verified by setting http_proxy variable and using lynx). I want to access this proxy over the internet (as an anonymizer) so that I can see how some ads show up for US traffic on my website. I have setup authentication so abuse is not a problem. However, I am not able to access the proxy over the internet. I have set the following rule in squid.conf http_access allow all Is this not possible to do what I want or I am missing something? The port 3128 is open in the firewall so that is not an issue. Squid is running on 0.0.0.0 Thanks Prateek

• Convert IP address string to binary in Python

  - by pizzim13

  As part of a larger application, I am trying to convert an IP address to binary. Purpose being to later calculate the broadcast address for Wake on LAN traffic. I am assuming that there is a much more efficient way to do this then the way I am thinking. Which is breaking up the IP address by octet, adding 0's to the beginning of each octet where necessary, converting each octet to binary, then combining the results. Should I be looking at netaddr, sockets, or something completely different? Example: From 192.168.1.1 to 11000000.10101000.00000001.00000001

• Arguments of using WCF/OData as access layer instead of EF/L2S/nHibernate directly

  - by Carl Hörberg

  We develop mostly low traffic but highly specialized web applications. Normally we use L2S, EF or nHibernate as access layer and then throws Asp.Net MVC to it and in which for normal crud operations we query the ISession/DataContext directly but for more advanced functions/side effects we put it in a some kind of service layer. Now, i was think about publishing the data through OData (WCF Data Service) and query that from the controllers (or even from jQuery when the a good template engine shows up) and publish the service operations through a WCF service (or as custom methods on the WCF Data Service?). What advantages/disadvantages does this architecture poses? Do I gain something except higher complexity and latency? Better separations of concerns (or is it just a illusion)?

• Rewrite rules for subfolders

  - by pg

  This may seem like a silly question but I can't figure it out. let's say I have a public_html folder with various folders like: Albatross, Blackbirds, Crows and Faqs. I want to make it so that any traffic to Albatross/faqs.php, Blackbirds/faqs.php, Crows/faqs.php etc will see the file that is at faqs/faqs.php?bird=albatross or faqs/faqs.php?bird=crows or what have you. If I go into the Albatross folder's .htaccess file I can do this RewriteRule faqs.php$ /faqs/faqs.php?cat=albatross[QSA] Which works fine, but I want to put something in the top level .htacces that works for all of them, so tried: RewriteRule faqs.php$ /faqs/faqs.php?cat=albatross[QSA] RewriteRule /(.*)/faqs.php$ /faqs/faqs.php?cat=$1 [QSA] and even RewriteRule /albatross/faqs.php$ /faqs/faqs.php?cat=albatross [QSA] and various others but nothing seems to work, when I go to http://www.birdsandwhatnot.com/albatross/faqs.php I see the same file the same way it's always been. Does the presence of an .htaccess file in the subfolder conflict with the higher up .htaccess file? Am I missing something?

• web2py or grok (zope) on a big portal,

  - by Robert

  Hi, I am planning to make some big project (1 000 000 users, approximately 500 request pre second - in hot time). For performance I'm going to use no relational dbms (each request could cost lot of instructions in relational dbms like mysql) - so i can't use DAL. My question is: how web2py is working with a big traffic, is it work concurrently? I'm consider to use web2py or Gork - Zope, How is working zodb(Z Object Database) with a lot of data? Is there some comparison with object-relational postgresql? Could you advice me please.

• Push DVCS repository to master without needing codebase

  - by Scorchin

  To work on a client's staging environment I have to connect through a VPN which locks all normal network traffic and prevents any connection to the Internet. This would immediately prevent any of the "normal" VCS solutions from being used as it's not possible to gain access to the server. A solution to this would be to create a DVCS repository (git?) locally and then push changes to the master, as and when needed. There is one flaw in this plan. The entire codebase is around 14GB. To download all of this over the internet would take some time, especially when I'm likely to be working on 3 or 4 different machines in each case. This seems silly and overkill for a DVCS. TL;DR Can any DVCS solution allow you to push to a master server/repo without needing the codebase? Bad example: copy the .git folder (not the 14GB codebase) to another directory and push this to the master once disconnected from the VPN.

• ISA Web Farm and WCF service hosted in a Windows Service with basicHttpBinding

  - by Ryan Pedersen

  I have created a WCF service that needs to be hosted in a Window Service because it is participating in a P2P mesh (NetPeerTcpBinding). When I tried to host the WCF Service with NetPeerTcpBinding endpoints in the IIS Service container the service wouldn't run because it turns out that the P2P binding doesn't work in IIS. I have exposed a HTTP endpoint from the WCF service hosted in a Windows Service container and I want to know if there is a way to create an ISA Web Farm that will route traffic to http endpoints on two machines each running the same WCF service in a Windows Service container.

• Tomcat cookies not working via my ProxyPass VirtualHost

  - by John

  Hi there. I'm having some issues with getting cookies to work when using a ProxyPass to redirect traffic on port 80 to a web-application hosted via Tomcat. My motivation for enabling cookies is to get rid of the "jsessionid=" parameter that is appended to the URLs. I've enabled cookies in my context.xml in META-INF/ for my web application. When I access the webapplication via http://url:8080/webapp it works as expected, the jsessionid parameter is not visible in the URL, instead it's stored in a cookie. When accessing my website via an apache2 virtualhost the cookies doesn't seem to work because now "jsessionid" is being appended to the URLs. How can I solve this issue? Here's my VHost configuration: <VirtualHost *:80 ServerName somedomain.no ServerAlias www.somedomain.no <Proxy * Order deny,allow Allow from all </Proxy ProxyPreserveHost Off ProxyPass / http://localhost:8080/webapp/ ProxyPassReverse / http://localhost:8080/webapp/ ErrorLog /var/log/apache2/somedomain.no.error.log CustomLog /var/log/apache2/somedomain.no.access.log combined </VirtualHost

• Transition domain to new web host without waiting for DNS propagation

  - by jcmoney

  I was considering switching to Amazon EC2 to host my website to handle more traffic. It seems like I would have to update DNS records to point to the new server but I was wondering if there was a way to avoid having to wait for the new DNS record to propagate. Putting the code on both hosts would not work for me since the app writes to a database pretty frequently. I thought about just using a meta redirect or php redirect on the old host to redirect to the new host ip but was wondering if there's a better more accepted way of doing this.

• which ASP.NET hosting site allows listening on different ports than 80 and uses .NET 4?

  - by ijjo

  I'm trying to take advantage of HTML 5 web sockets in .NET and the easiest way appears to be something like what this guy does. I've already tested this myself and it works great, but there are a few problems if I try to deploy this to my hosting site (discountasp.net). Basically, I am not allowed to open up a port on 8080 and listen on it. I then tried to figure out a way to listen on port 80 with IIS as well, but using the HTTPListener, I run into sercurity issues as well. This doesn't seem like it will help since I can't mess with this stuff on the hosting site server either. So to make my life easier, I think I need to find a hosting site that simply allows me to open up a socket on port 8080 and listen on it. Anyone know of one? Or does anyone know of a workaround (besides sniffing all the traffic on port 80)?

• Best tools to monitor Tomcat

  - by Pier Luigi

  Hi all, I'm searching free tools for monitor tomcat (traffic, memory usage, threads, requests, CPU, logs,...). I'm currently using lambdaprobe on Tomcat 5.5.x, but it seems that is no more developed (or not? the site lambdaprobe.org is always down for me...). Has someone good experiences to share? In lambdaprobe there are some info available only if tomcat is instrumented with JMX. Well, JMX is something of strange and mysterious for me. Is a good solution in a production server? It's worth to spend my (little) time to learn it?

• Qt QNetworkAccessManager does not emit signals

  - by Emilio

  The function CheckSite() is called with an url like http://site.com, it initializes a QNetworkAccessManager object and connect() slots and signals. The manger-get() call seems work (it generates http traffic) but does not call the slot replyFinished() at the request end. What's wrong with this code? #include <QtCore> #include <QtNetwork> class ClientHandler : public QObject { Q_OBJECT QNetworkAccessManager *manager; private slots: void replyFinished(QNetworkReply *); public: void CheckSite(QString url); }; void ClientHandler::replyFinished(QNetworkReply *reply) { qDebug() << "DONE"; } void ClientHandler::CheckSite(QString url) { QUrl qrl(url); manager = new QNetworkAccessManager(this); connect(manager, SIGNAL(finished(QNetworkReply*)), this, SLOT(replyFinished(QNetworkReply*))); manager->get(QNetworkRequest(qrl)); }

• Message Queue or Scheduler

  - by Walter White

  Hi all, I am currently using Quartz Scheduler for asynchronous tasks such as sending an email when an exception occurs, sending an email from the web interface, or periodically analyzing traffic. Should I use a message queue for sending an email? Is it any more efficient or correct to do it that way? The scheduler approach works just fine. If I use a queue and the email failed to send, is it possible for the queue to retry sending the email at a later time? The queue approach looks simpler than the scheduler for tasks that need to happen immediately, but for scheduler tasks, the scheduler still, unless there is more to the queue than I am aware of. I have not yet used JMS, so this is what I have read. Walter

• MTU mismatch between GetIfEntry and netsh

  - by ChrisJ

  I'm working on pseudo-transport layer software that runs over UDP, providing reliable connection-oriented transmission, as an alternative to TCP. In order to maximize network efficiency, we query the MTU of the "best" network adapter upon initialization. MIB_IFROW row = {0}; row.dwIndex = dwBestIfIndex; dwRes = GetIfEntry(&row); Searching online I found that you can use the following netsh commands to query for this same value, from a command prompt (not a C++ API) netsh interface ipv4 show interfaces netsh interface ipv4 show subinterfaces The troubling issue is that while row.dwMtu may be set to 1500, snooping the network traffic on the sending laptop shows that our packets are fragmented into 1300 byte packets. netsh also reports that the MTU is 1300. Clearly the value reported by netsh command is the actual used values. Anyone know what API I can call to get the same values as netsh?

• What's your hobby website; do you maintain it for your users or yourself?

  - by Glennular

  What is your hobby website? Do you care if it has high traffic or is it more for personal satisfaction? When deciding on the features to implement are you taking in to consideration the needs of general user-base or features you really want to build? What balance do you use to keep yourself satisfied as well as your users? When do you feel your site is able to release to the world? Do you release it initially and hope for anticipatory beta group? or wait till you have a solid built set of features?

• Server Side of UpdatePanel don't understand PartialPostback

  - by jaderanderson

  This erros seems to happen randomly and in the whole system. Sometimes when we click in a button, or even try to login, a alert comes up with the "Message cannot be parsed" error. Funny thing is that when I turn on fiddler, the thing stars to function ok. Sniffing the connection via smsniff i was able to capture the traffic of the bugged and working postbacks. The contents were suposed to be rendered in a update panel. It appears that the "bugged" response is the whole page again, what would cause such a thing? Sorry about the undetailed question, my first here. Regards

• FCGI htaccess handler

  - by sharvey

  I'm trying to setup django on a shared hosting provider. I followed the instructions on http://helpdesk.bluehost.com/index.php/kb/article/000531 and almost have it working. The problem I'm facing now is that the traffic is properly routed throught the fcgi file, but the file itself shows up as plain text in the browser. If I run ./mysite.fcgi in the ssh shell, I do get the default django welcome page. my .htaccess is: AddHandler fastcgi-script .fcgi RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ mysite.fcgi/$1 [QSA,L] and mysite.fcgi: #!/usr/bin/python2.6 import sys, os os.environ['DJANGO_SETTINGS_MODULE'] = "icm.settings" from django.core.servers.fastcgi import runfastcgi runfastcgi(method="threaded", daemonize="false") thanks.
