  • mod_rewrite - strange [R] behavior

    - by Tal
    Hello! I'm doing something very simple with mod_rewrite and it's behaving strange. It's behaving as if I'm using the [R] option, but I'm not. Here's a simple test for a .htaccess file: RewriteEngine on RewriteRule ^page1$ page2 This should redirect a request for page1 to page2, but leave the URL in the web browser still pointing to page1. That doesn't happen though. It actually switches the URL to page2, as if I were using this code: RewriteRule ^page1$ page2 [R] Why's it doing that? That's not the default behavior. I'm using a pre-configured machine I got for EC2, so it's probably something in the apache configuration I'm not aware of. Googling has been futile. Help? This is Apache 2.12 btw.

  • Time for creation of database on site

    - by slo2ols
    Hi. When and where would you create database to develop web site using ASP.NET MVC 2 and Entity Framework 4 (CreateDatabase method). I think about first run of web site and redirect on welcome page, when controller creates database from model. But I doubt about details: 1. Where? In HttpModule, but request of any image or css will check that database exist. In custom RouteHandler, but then anybody need to know that need to use this handler when to add route. In BaseController, but then code will look like SomeController(..., IDatabase database) : base(database). 2. When? Better create database on first run by any url or may be on deployment of site (additional tool which create ObjectContext and invoke CreateDatabase)? Thanks.

  • extended permissions

    - by melimoreno
    Hi i'm doing a fb app that update the status box(what's in your mind), i'm using set_status from facebooker .. first i have this error: set_status needs extended permission so i google it and find this: before_filter :ensure_has_status_update .. so i put it in my controller and that solves the problem, but when i try to update the status, all ways redirect me to a fb page that says: You have already granted permissions to this application. so i go to the controller comment before_filter :ensure_has_status_update and then go to my app again and it works.. so i want to do this if (has_status_update == false) ask for permision else update the status i google it for a long time but i can't find an answer..

  • Refreshing the asp.net web page after validation

    - by user279521
    Hi, I have an asp.net web page (C# 2008) where the user would enter an EmployeeID, and when they tab out of the textbox, they get a messagebox prompting them to select one of two values from a dropdown listbox. The code for the message prompt in the codebehind is : Response.Write("<script>window.alert('Please select Alpha or Beta')</script>"); After the prompt is displayed, and the user clicks "ok" and returns to the page, the text on the page appears distorted (the text in labels are a size larger, the labels get wrapped to another line etc) I tried putting a Response.Redirect("UserProfileMaint.aspx"); after the messagebox in the codebehind, but now, the messagebox does not appear; I want to display the messagebox validation, and ensure the appearance of the text on the page is not distorted. How can I do this?

The function I use for the redirect is header ('Location: mypage2.html'); exit (); But I want the new page to open in _top location, not inside the same IFRAME that I use. How can I tell the browser to open the new page in _top not inside the IFRAME? Thanks in advance.

  • RSpec "undefined local variable or method `user'"

    - by Justin
    I have the following test written in RSpec: describe '#create' do ... it 'redirects users to profile page' do response.should redirect_to user_path(user) end ... ... And the following in my UsersController: def create @user = User.new(params[:user]) if @user.save redirect_to user_path(@user) end end Does anyone know why this is returning the following error: NameError: undefined local variable or method 'user' I also tried changing this to be root_url in both cases instead of user_path(user) and it gave a different error saying: Expected response to be a <:redirect>, but was <200> Does anyone know what the issue might be? I have double-checked my code and have seen similar questions posted online, but haven't been able to find a solution. Thanks in advance for any help!

  • What causes session/forms authentication timeouts in MVC3

    - by SimpleUser
    Can somebody please let me know what are the reasons for your authentication to die suddenly, even when you are working on an application without any idle time? Both with and without AJAX calls. And what are the different reasons for getting a 302 redirect from an MVC3 application to the Logon page. Been struggling with an issue with timeouts that happen at random. Sometimes within a few minutes of login to the application and sometimes you can go for hours (with/without idle time) without being thrown out. Thank You

  • ExpressJS: What is the difference between app.local and res.local?

    - by aeyang
    I'm trying to learn Express and in my app I have middleware that passes the session object from the Request object to my Response object so that I can access it in my views: app.use((req, res, next) -> res.locals.session = req.session next() ) But app.locals is available to the view as well right? So is it the same if I do app.locals.session = req.session? Is there a convention for the types of things app.locals and res.locals are used for? I was also confused on what the difference is between res.render() and res.redirect()? When should each be used? Thanks for reading. Any help related to Express is appreciated!

  • Form Login Error

    - by ilp
    I'm having issues with a login form for my website. At the top of the login.php form I have this <?php if (isset($_SESSION['username'])){ header("Location: http://myurl/"); die;}?> <?php require 'includes/dbconnect.php' ; ?> <?php require 'includes/header.php'; ?> and when login is successful I redirect them to header('Location: http://myrul/'); Header.php has <?php session_start(); ?> at the top.

  • asp.net web application - server side canceling Submit PostBackUrl if not(!) Page.IsValid

    - by Brent
    Thanks for any help I have a web application, and the submit uses the PostBackUrl to display data if the form is valid. I need to use different (server side) validation groups, depending on what radiobutton is selected. That is, manually call Page.Validate('ValidationGroupA'). The validation itself is working fine, in terms of Page.IsValid correctly assigned true or false. however, if the page is not valid, the page redirects to the page specified by PostBackUrl on the submit button, where the page is found not to be valid, and the client redirected back with: if (!PreviousPage.IsValid){Response.Redirect("DataEntryPage.aspx");}) However, by getting to here and back again, all form data is lost, and the relevant validation controls and summaries are not displayed. is there an equivalent of javascripts evt.preventDefault() or some other way, once it is detected validation has failed after a manual call to Page.Validate to post the form back with appropriate validation errors displayed? Thank you.

  • Load the main page if user visits a page meant for an ajax request?

    - by QAZ
    Hello, I am using jQuery for a simple website and have a main page 'index.html' which can load some content (e.g. 'info1.html' or 'info2.html') via jQuery ajax requests, and display the result of these requests inside an element in the 'index.html' page. If a user somehow visits say 'info1.html' directly, is their a way to redirect or load the main 'index.html' page? (or what's best practice for this type of thing) as Google is indexing all the small html files used for the ajax requests and sometimes a user can click into the site via these pages. Thanks.

  • [iPhone] Selling something inside an application

    - by Nonepse
    Hi, I've heard there are some precautions to take to develop a market in an application. I'm developing an application for a football club. I would like to integrate a kind of market to sell stadium seats. Someone told me Apple will refuse the application if I integrate it directly inside the app (using Obj-C, communicating with PHP pages). According to him, I should redirect the user to an external web page (using Safari app for example) to realize the transaction. Apple does not really communicate about that kind of information. Do you know anything about it ? Thanks for any help !

  • JQuery mobile handling links (return false)

    - by shinax
    I'm planning on using JQM to make a simple mobile web app, and I'm having problems getting this simple functionality to work: when I click on some links (not all of them), I want to be able to first process some data, and then depending on that outcome, sometimes continue the link action (I like the whole transitions and ajax things), and sometimes don't. The important part is that I want to preserve the normal JQMobile transitions and stuff for the links, just sometimes prevent them (for example for validation and things like that). I've tried with: return false, preventDefault (and in combination with stopPropagation), and data-ajax="false", and none hav worked, they all redirect. Could somebody tell me the correct way to to this in JQMobile? Just in case it's important: I'm using anchor links, using this to test. Thank you in advance, Jennifer.

    I have a form where a user input name and other contact information. I validate the input and then redirect to a thank you page. I wanted to personalize the page by having the user name appear as part of the thank you note. I tried document.getElementById(Name1).value to retrieve the value of the Name but it it is giving Undefined. Is there a way for me to set the value of the Name1 field to another variable that I call again to include it in my text message?

When you need a different shutdown # approach you can use one of the following variables: # o ssl-unclean-shutdown: # This forces an unclean shutdown when the connection is closed, i.e. no # SSL close notify alert is send or allowed to received. This violates # the SSL/TLS standard but is needed for some brain-dead browsers. Use # this when you receive I/O errors because of the standard approach where # mod_ssl sends the close notify alert. # o ssl-accurate-shutdown: # This forces an accurate shutdown when the connection is closed, i.e. a # SSL close notify alert is send and mod_ssl waits for the close notify # alert of the client. This is 100% SSL/TLS standard compliant, but in # practice often causes hanging connections with brain-dead browsers. Use # this only for browsers where you know that their SSL implementation # works correctly. # Notice: Most problems of broken clients are also related to the HTTP # keep-alive facility, so you usually additionally want to disable # keep-alive for those clients, too. Use variable "nokeepalive" for this. # Similarly, one has to force some clients to use HTTP/1.0 to workaround # their broken HTTP/1.1 implementation.

  • Why is Varnish not caching?

If I'm understanding correctly, this means the file isn't being returned from Varnish's cache. Is there a problem with my Varnish config?

  • Querying Networking Statistics: dlstat(1M)

    - by user12612042
    Oracle Solaris 11 took another big leap forward in networking technologies providing a reliable, secure and scalable infrastructure to meet the growing needs of today's datacenter implementations. Oracle Solaris 11 introduced a new and powerful network stack architecture, also known as Project Crossbow. From Solaris 11 onwards, we introduced a command line tool viz. dlstat(1M) to query network statistics. dlstat (for datalink statistics) is a statistics querying counterpart for dladm(1M) - the datalink administration tool. The tool is very easy to get started. Just type dlstat on a shell prompt on Solaris 11 (or later). For example,: # dlstat LINK IPKTS RBYTES OPKTS OBYTES net0 834.11K 145.91M 575.19K 104.24M net1 7.87K 2.04M 0 0 In this example, the system has two datalinks net0 and net1. The output columns denote input packets/bytes as well as output packets/bytes. The numbers are abbreviated in xxx.xxUnit format. However, one could get the actual counts by simply running dlstat -u R (R for raw): # dlstat -u R LINK IPKTS RBYTES OPKTS OBYTES net0 834271 145931244 575246 104242934 net1 7869 2036958 0 0 In addition, dlstat also supports various subcommands dlstat help The following subcommands are supported: Stats : show-aggr show-ether show-link show-phys show-bridge For more info, run: dlstat help {default|} I will only describe couple of interesting subcommands/options here. For a comprehensive description of all the dlstat subcommands refer dlstat's official manual . For NICs that support multiple rings (e.g. ixgbe), dlstat show-phys -r allows us to query per Rx ring statistics. For example: dlstat show-phys -r net4 LINK TYPE INDEX IPKTS RBYTES net4 rx 0 0 0 net4 rx 1 0 0 net4 rx 2 0 0 net4 rx 3 0 0 net4 rx 4 0 0 net4 rx 5 0 0 net4 rx 6 0 0 net4 rx 7 0 0 In this case, net4 is just a vanity name for an ixgbe datalink. This view is especially useful if one wants to look at the network traffic spread across all the available rings. Furthermore, any of the dlstat commands could be run with -i option to periodically query and display stats. For example, running dlstat show-phys -r net4 -i 5 will emit per Rx ring stats every 5 seconds. This is especially useful while analyzing a live system. Similarly, dlstat show-phys -t could be used to query per Tx ring stats. -r and -t could also be combined as dlstat show-phys -rt to query both Rx as well as Tx stats at the same time. Finally, there is also a quick way to dump ALL the stats. Just run dlstat -A. You probably want to redirect this output to a file because you are going to get a whole load of stats :-).

  • Deploying Socket.IO App to Windows Azure Web Site with Azure CLI

    - by shiju
    In this blog post, I will demonstrate how to deploy Socket.IO app to Windows Azure Website using Windows Azure Cross-Platform Command-Line Interface, which leverages the Windows Azure Website’s new support for Web Sockets. Recently Windows Azure has announced lot of enhancements including the support for Web Sockets in Windows Azure Websites, which lets the Node.js developers deploy Socket.IO apps to Windows Azure Websites. In this blog post, I am using  Windows Azure CLI for create and deploy Windows Azure Website. Install  Windows Azure CLI The Windows Azure CLI available as a NPM module so that you can install Windows Azure CLI using  NPM as shown in the below command. After installing the azure-cli, just enter the command “azure” which will show the useful commands provided by Azure CLI. Import Windows Azure Subscription Account In order to import our Azure subscription account, we need to download the Windows Azure subscription profile. The Azure CLI command “account download” lets you download the  Windows Azure subscription profile as shown in the below command. The command redirect you login to Windows Azure portal and allow you to download the Windows Azure publish settings file. The account import command lets you import the downloaded publish settings file so that you can create and manage Websites, Cloud Services, Virtual Machines and Mobile Services in Windows Azure. Create Windows Azure Website and Enable Web Sockets In this post, we are going to deploy Socket.IO app to Windows Azure Website by using the Web Socket support provided by Windows Azure. Let’s create a Website named “socketiochatapp” using the Azure CLI. The above command will create a Windows Azure Website that will also initialize a Git repository with a remote named Azure. We can see the newly created Website from Azure portal. By default, the Web Sockets will be disabled. So let’s enable it by navigating to the Configure tab of the Website, and select “ON” in Web Sockets option and save the configuration changes. Deploy a Node.js Socket.IO App to Windows Azure Now, our Windows Azure Website supports Web Sockets so that we can easily deploy Socket.IO app to Windows Azure Website. Let’s add Node.js chat app which leverages Socket.IO module. Please note that you have to add npm module dependencies in the package.json file so that Windows Azure can install the dependencies when deploying the app. Let’s add the Node.js app and add the files to git repository. Let’s commit the changes to git repository. We have committed the changes to git local repository. Let’s push the changes to Windows Azure production environment. The successful deployment can see from the Windows Azure portal by navigating to the deployments tab of the selected Windows Azure Website. The screen shot below shows that our chat app is running successfully.   You can follow me on Twitter @shijucv

  • Changing the default installation path to a newly installed hard disk

    - by mgj
    Hi, I am currently working on a dual-booted PC. I am using Windows XP and Ubuntu 10.04 Lucid Lynx released in April 2010. The allocated partition to Ubuntu that I am making use of has almost exhausted. Current memory allocations on the PC wrt Ubuntu OS looks like this: bodhgaya@pc146724-desktop:~$ df -h Filesystem Size Used Avail Use% Mounted on /dev/sda2 8.6G 8.0G 113M 99% / none 998M 268K 998M 1% /dev none 1002M 580K 1002M 1% /dev/shm none 1002M 100K 1002M 1% /var/run none 1002M 0 1002M 0% /var/lock none 1002M 0 1002M 0% /lib/init/rw /dev/sda1 25G 16G 9.8G 62% /media/C /dev/sdb1 37G 214M 35G 1% /media/ubuntulinuxstore bodhgaya@pc146724-desktop:~$ cd /tmp I am trying to mount a 40GB(/dev/sdb1 - given below) new hard disk along with my existing Ubuntu system to overcome with hard disk space related issues. I referred to the following tutorial to mount a new hard disk onto the system:- http://www.smorgasbord.net/how-to-in...untu-linux%20/ I was able to successfully mount this hard disk for Ubuntu 0S. I have this new hard disk setup in /media/ubuntulinuxstore directory. The current partition in my system looks like this: bodhgaya@pc146724-desktop:/media/ubuntulinuxstore$ sudo fdisk -l [sudo] password for bodhgaya: Disk /dev/sda: 40.0 GB, 40000000000 bytes 255 heads, 63 sectors/track, 4863 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x446eceb5 Device Boot Start End Blocks Id System /dev/sda1 * 2 3264 26210047+ 7 HPFS/NTFS /dev/sda2 3265 4385 9004432+ 83 Linux /dev/sda3 4386 4863 3839535 82 Linux swap / Solaris Disk /dev/sdb: 40.0 GB, 40000000000 bytes 255 heads, 63 sectors/track, 4863 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xfa8afa8a Device Boot Start End Blocks Id System /dev/sdb1 1 4862 39053983+ 7 HPFS/NTFS bodhgaya@pc146724-desktop:/media/ubuntulinuxstore$ Now, I have a concern wrt the "location" where the new softwares will be installed. Generally softwares are installed via the terminal and by default a fixed path is used to where the post installation set up files can be found (I am talking in context of the drive). This is like the typical case of Windows, where softwares by default are installed in the C: drive. These days people customize their installations to a drive which they find apt to serve their purpose (generally based on availability of hard disk space). I am trying to figure out how to customize the same for Ubuntu. As we all know the most softwares are installed via commands given from the Terminal. My road block is how do I redirect the default path set on the terminal where files get installed to this new hard disk. This if done will help me overcome space constraints I am currently facing wrt the partition on which my Ubuntu is initially installed. I would also by this, save time on not formatting my system and reinstalling Ubuntu and other softwares all over again. Please help me with this, your suggestions are much appreciated.

  • Virtual host is not working in Ubuntu 14 VPS using XAMPP 1.8.3

    - by viral4ever
    I am using XAMPP as server in ubuntu 14.04 VPS of digitalocean. I tried to setup virtual hosts. But it is not working and I am getting 403 error of access denied. I changed files too. My files with changes are /opt/lampp/etc/httpd.conf # # This is the main Apache HTTP server configuration file. It contains the # configuration directives that give the server its instructions. # See <URL:http://httpd.apache.org/docs/trunk/> for detailed information. # In particular, see # <URL:http://httpd.apache.org/docs/trunk/mod/directives.html> # for a discussion of each configuration directive. # # Do NOT simply read the instructions in here without understanding # what they do. They're here only as hints or reminders. If you are unsure # consult the online docs. You have been warned. # # Configuration and logfile names: If the filenames you specify for many # of the server's control files begin with "/" (or "drive:/" for Win32), the # server will use that explicit path. If the filenames do *not* begin # with "/", the value of ServerRoot is prepended -- so 'log/access_log' # with ServerRoot set to '/www' will be interpreted by the # server as '/www/log/access_log', where as '/log/access_log' will be # interpreted as '/log/access_log'. # # ServerRoot: The top of the directory tree under which the server's # configuration, error, and log files are kept. # # Do not add a slash at the end of the directory path. If you point # ServerRoot at a non-local disk, be sure to specify a local disk on the # Mutex directive, if file-based mutexes are used. If you wish to share the # same ServerRoot for multiple httpd daemons, you will need to change at # least PidFile. # ServerRoot "/opt/lampp" # # Mutex: Allows you to set the mutex mechanism and mutex file directory # for individual mutexes, or change the global defaults # # Uncomment and change the directory if mutexes are file-based and the default # mutex file directory is not on a local disk or is not appropriate for some # other reason. # # Mutex default:logs # # Listen: Allows you to bind Apache to specific IP addresses and/or # ports, instead of the default. See also the <VirtualHost> # directive. # # Change this to Listen on specific IP addresses as shown below to # prevent Apache from glomming onto all bound IP addresses. # #Listen 12.34.56.78:80 Listen

  • Looking into ASP.Net MVC 4.0 Mobile Development - part 2

    - by nikolaosk
    In this post I will be continuing my discussion on ASP.Net MVC 4.0 mobile development. You can have a look at my first post on the subject here . Make sure you read it and understand it well before you move one reading the remaining of this post. I will not be writing any code in this post. I will try to explain a few concepts related to the MVC 4.0 mobile functionality. In this post I will be looking into the Browser Overriding feature in ASP.Net MVC 4.0. By that I mean that we override the user agent for a given user session. This is very useful feature for people who visit a site through a device and they experience the mobile version of the site, but what they really want is the option to be able to switch to the desktop view. "Why they might want to do that?", you might wonder.Well first of all the users of our ASP.Net MVC 4.0 application will appreciate that they have the option to switch views while some others will think that they will enjoy more the contents of our website with the "desktop view" since the mobile device they view our site has a quite large display.  Obviously this is only one site. These are just different views that are rendered.To put it simply, browser overriding lets our application treat requests as if they were coming from a different browser rather than the one they are actually from. In order to do that programmatically we must have a look at the System.Web.WebPages namespace and the classes in it. Most specifically the class BrowserHelpers. Have a look at the picture below   In this class we see some extension methods for HttpContext class.These methods are called extensions-helpers methods and we use them to switch to one browser from another thus overriding the current/actual browser. These APIs have effect on layout,views and partial views and will not affect any other ASP.Net Request.Browser related functionality.The overridden browser is stored in a cookie. Let me explain what some of these methods do. SetOverriddenBrowser() -  let us set the user agent string to specific value GetOverriddenBrowser() -  let us get the overridden value ClearOverriddenBrowser() -  let us remove any overridden user agent for the current request   To recap, in our ASP.Net MVC 4.0 applications when our application is viewed in our mobile devices, we can have a link like "Desktop View" for all those who desperately want to see the site with in full desktop-browser version.We then can specify a browser type override. My controller class (snippet of code) that is responsible for handling the switching could be something like that. public class SwitchViewController : Controller{ public RedirectResult SwitchView(bool mobile, string returnUrl){if (Request.Browser.IsMobileDevice == mobile)HttpContext.ClearOverriddenBrowser();elseHttpContext.SetOverriddenBrowser(mobile ? BrowserOverride.Mobile : BrowserOverride.Desktop);return Redirect(returnUrl);}} Hope it helps!!!!

  • PHP MVC error handling, view display and user permissions

    - by cen
    I am building a moderation panel from scratch in a MVC approach and a lot of questions cropped up during development. I would like to hear from others how they handle these situations. Error handling Should you handle an error inside the class method or should the method return something anyway and you handle the error in controller? What about PDO exceptions, how to handle them? For example, let's say we have a method that returns true if the user exists in a table and false if he does not exist. What do you return in the catch statement? You can't just return false because then the controller assumes that everything is alright while the truth is that something must be seriously broken. Displaying the error from the method completely breaks the whole design. Maybe a page redirect inside the method? The proper way to show a view The controller right now looks something like this: include('view/header.php'); if ($_GET['m']=='something') include('view/something.php'); elseif ($_GET['m']=='somethingelse') include('view/somethingelse.php'); include('view/foter.php'); Each view also checks if it was included from the index page to prevent it being accessed directly. There is a view file for each different document body. Is this way of including different views ok or is there a more proper way? Managing user rights Each user has his own rights, what he can see and what he can do. Which part of the system should verify that user has the permission to see the view, controller or view itself? Right now I do permission checks directly in the view because each view can contain several forms that require different permissions and I would need to make a seperate file for each of them if it was put in the controller. I also have to re-check for the permissions everytime a form is submitted because form data can be easily forged. The truth is, all this permission checking and validating the inputs just turns the controller into a huge if/then/else cluster. I feel like 90% of the time I am doing error checks/permissions/validations and very little of the actual logic. Is this normal even for popular frameworks?
