  • How to internally rewrite a page when requested from specific HTTP_HOST

    - by Andy
    Hi all, I have a Drupal site, site.com, and our client has a campaign that they're promoting for which they've bought a new domain name, campaign.com. I'd like it so that a request for campaign.com internally rewrites to a particular page of the Drupal site. Note Drupal uses an .htaccess file in the document root. The normal Drupal rewrite is # Rewrite URLs of the form 'x' to the form 'index.php?q=x'. RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} !=/favicon.ico RewriteRule ^(.*)$ index.php?q=$1 [L,QSA] I added the following before the normal rewrite. # Custom URLS (eg. microsites) go here RewriteCond %{HTTP_HOST} =campaign.com RewriteCond %{REQUEST_URI} =/ RewriteRule ^ index.php?q=node/22 [L] Unfortunately it doesn't work, it just shows the homepage. Turning on the rewrite log I get this. 1. [rid#2da8ea8/initial] (3) [perdir D:/wamp/www/] strip per-dir prefix: D:/wamp/www/ - 2. [rid#2da8ea8/initial] (3) [perdir D:/wamp/www/] applying pattern '^' to uri '' 3. [rid#2da8ea8/initial] (2) [perdir D:/wamp/www/] rewrite '' - 'index.php?q=node/22' 4. [rid#2da8ea8/initial] (3) split uri=index.php?q=node/22 - uri=index.php, args=q=node/22 5. [rid#2da8ea8/initial] (3) [perdir D:/wamp/www/] add per-dir prefix: index.php - D:/wamp/www/index.php 6. [rid#2da8ea8/initial] (2) [perdir D:/wamp/www/] strip document_root prefix: D:/wamp/www/index.php - /index.php 7. [rid#2da8ea8/initial] (1) [perdir D:/wamp/www/] internal redirect with /index.php [INTERNAL REDIRECT] 8. [rid#2da7770/initial/redir#1] (3) [perdir D:/wamp/www/] strip per-dir prefix: D:/wamp/www/index.php - index.php 9. [rid#2da7770/initial/redir#1] (3) [perdir D:/wamp/www/] applying pattern '^' to uri 'index.php' 10.[rid#2da7770/initial/redir#1] (3) [perdir D:/wamp/www/] strip per-dir prefix: D:/wamp/www/index.php - index.php 11.[rid#2da7770/initial/redir#1] (3) [perdir D:/wamp/www/] applying pattern '^(.*)$' to uri 'index.php' 12.[rid#2da7770/initial/redir#1] (1) [perdir D:/wamp/www/] pass through D:/wamp/www/index.php I'm not used to mod_rewrite, so I might be missing something, but comparing the logs from a call to http://site.com/node/3 and from http://campaign.com/ I can't see any meaningful difference. Specifically uri and args on line 4 seem correct, the internal redirect on line 7 seems right, and the pass through on line 12 seems right (because the file index.php exists). But for some reason it seems the query string's been discarded/ignored around the time of the internal redirect. I'm completely stumped. Also, if anyone could provide a reference on understanding the rewrite log, that might help. It'd be great if there's a way to track the query string through the internal redirect. FWIW I'm using WampServer 2.1 with Apache 2.2.17.

  • Parsing HTML using HtmlParser

    - by Blankman
    My html has 20 or so rows of the following HTML pattern. So the below is considered a single instance of the pattern. Each instance of this pattern represents a product. Again the below is a single instance, it spans multiple rows in the HTML table. <table> .. <!-- product starts here, this html comment is not in the real html --> <tr> <td rowspan="5" class="product" valign="top"><nobr> ????????????</td> </tr> <tr> <td class="title" ??????????>?????????</td> <td class="title" ??????????>?????????</td> <td class="title" ??????????>?????????</td> <td class="title" ??????????>?????????</td> <td class="title" ??????????>?????????</td> <td class="title" ??????????>?????????</td> </tr> <tr> <td class="data" ?????? </td> <td class="data" ?????? </td> <td class="data" ?????? </td> <td class="data" ?????? </td> <td class="data" ?????? </td> <td class="data" ?????? </td> </tr> </tr> <tr> <td colspan="5" ????????</td> </tr> <tr> <td colspan="6" width="100%">&nbsp;<hr></td> </tr> <!-- product ends here, this html comment is not in the real html --> <!-- above pattern repeats multiple times in the HTML --> .. <table> I am trying to use HtmlParser for this. Parser rowParser = new Parser(); rowParser.setInputHtml(page.getHtml()); // page object represents a html page rowParser.setEncoding("UTF-8"); NodeFilter productRowFilter = new AndFilter( new TagNameFilter("tr"), new HasChildFilter( new AndFilter( new TagNameFilter("td"), new HasAttributeFilter("class", "product"))) The above filter doesn't work, just showing you what I have so far. I need to somehow combine these filters, and use the last td to mark the end of the pattern i.e. the td with the colspan=6 and width=100% with child element hr. I have been struggling with this, and have resorted to Regex'ing but was told numerous times to NOT use regex for html parsing, so here I am! Your help is much appreciated!

  • Why meta refresh followed by 2 redirects?

    - by twneale
    I have encountered several websites where the initial visit by a user results in a http-equiv refresh to another (usually gibberish) url, which then promptly redirects (302) to another gibberish url, which in turn immediately redirects to yet a fourth url that actually displays the landing page for the site. My question is: what the heck? Why would a server be set up to behave this way? Here is list of a few sites that do this: New York State Library - http://nysl.nysed.gov New York State Regulations provided by Westlaw - http://government.westlaw.com/linkedslice/default.asp?SP=nycrr-1000

  • Facebook Oauth 2.0 Token errors

    - by James
    The user clicks the URL that is generated via the code below. $url = 'https://graph.facebook.com/oauth/authorize?' . http_build_query(array('client_id' => FACEBOOK_APP_ID, 'redirect_uri' => 'http://fb.example.com/facebook', 'scope' => 'publish_stream,email,offline_access,user_location,user_hometown', 'display' => 'page')); Upon granting access to the application, and redirecting to http://fb.example.com/facebook I grab the following URL using cURL. $url = 'http://graph.facebook.com/oauth/access_token?' . http_build_query(array('client_id' => FACEBOOK_APP_ID, 'client_secret' => FACEBOOK_SECRET, 'redirect_uri' => 'http://fb.example.com/facebook', 'code' => $params['code'])); This returns the error below that I receive when grabbing the above URL. { "error": { "type": "OAuthException", "message": "Error validating verification code." } } Any ideas? Really getting stuck on this.

  • How can I use django.core.files.File

    - by Jake
    The docs for django.core.files.File imply I can do this: print File(open(path)).url but the File object has no attribute 'url' However, django.db.models.fields.files.FieldFile extends File and does have all the attributes described in the docs for File, but I can't create one without giving it a model field. All I want it something that does what the docs for django.core.files.File (link above) say it does, take a python file and give it attributes like 'url' and 'path' and 'name', can anyone help? Cheers, Jake

  • Multiple "pages" in GWT with human friendly URLs

    - by Andreas Borglin
    Hi. I'm playing with a GWT/GAE project which will have three different "pages", although it is not really pages in a GWT sense. The top views (one for each page) will have completely different layouts, but some of the widgets will be shared. One of the pages is the main page which is loaded by the default url (http://www.site.com), but the other two needs additional URL information to differentiate the page type. They also need a name parameter, (like http://www.site.com/project/project-name. There are at least two solutions to this that I'm aware of. Use GWT history mechanism and let page type and parameters (such as project name) be part of the history token. Use servlets with url-mapping patterns (like /project/*) The first choice might seem obvious at first, but it has several drawbacks. First, a user should be able to easily remember and type URL directly to a project. It is hard to produce a human friendly URL with history tokens. Second, I'm using gwt-presenter and this approach would mean that we need to support subplaces in one token, which I'd rather avoid. Third, a user will typically stay at one page, so it makes more sense that the page information is part of the "static" URL. Using servlets solves all these problems, but also creates other ones. So my first questions is, what is the best solution here? If I would go for the servlet solution, new questions pop up. It might make sense to split the GWT app into three separate modules, each with an entry point. Each servlet that is mapped to a certain page would then simply forward the request to the GWT module that handles that page. Since a user typically stays at one page, the browser only needs to load the js for that page. Based on what I've read, this solution is not really recommended. I could also stick with one module, but then GWT needs to find out which page it should display. It could either query the server or parse the URL itself. If I stick with one GWT module, I need to keep the page information stored on server side. Naturally I thought about sessions, but I'm not sure if its a good idea to mix page information with user data. A session usually lives between user login and logout, but in this case it would need different behavior. Would it be bad practise to handle this via sessions? The one GWT module + servlet solution also leads to another problem. If a user goes from a project page to the main page, how will GWT know that this has happened? The app will not be reloaded, so it will be treated as a simple state change. It seems rather ineffecient to have to check page info for every state change. Anyone care to guide me out of the foggy darkness that surrounds me? :-)

    Much like you can map out volcanic eruptions to create a neat pattern around the Pacific Ring of Fire, you can also map out hurricanes and tropical storms. Check out this high-resolution visualization to see the pattern formed by a century and a half of storms. Courtesy of UXBlog and data from the National Oceanic and Atmospheric Administration, the above projection shows the path of tropical storms around the equator (the perspective, if the map looks unfamiliar to you, is bottom up with Antarctica and the lower portion of South America in the center).

  • Flash swf to play PCM WAV files?

    - by Geuis
    I am in need of a Flash swf that is capable of loading PCM WAV files via a url passed to it. An example of the file can be found here: http://msdn.microsoft.com/en-us/library/ff512405.aspx The swf does not need a visible interface, as it is meant for audio playing only and not user interaction. The swf should have a simple javascript interface for page-level interactions. These include: load(url): loads a PCM WAV file over the internet using the url that is passed through it. play(): Should play the PCM WAV file that was loaded stop(): Should stop playing the current file. I can provide a sample audio file that matches the specifications if the developer is unable to obtain a url from the link posted above.

  • StreamInsight and Reactive Framework Challenge

    In his blogpost Roman from the StreamInsight team asked if we could create a Reactive Framework version of what he had done in the post using StreamInsight.  For those who don’t know, the Reactive Framework or Rx to its friends is a library for composing asynchronous and event-based programs using observable collections in the .Net framework.  Yes, there is some overlap between StreamInsight and the Reactive Extensions but StreamInsight has more flexibility and power in its temporal algebra (Windowing, Alteration of event headers) Well here are two alternate ways of doing what Roman did. The first example is a mix of StreamInsight and Rx var rnd = new Random(); var RandomValue = 0; var interval = Observable.Interval(TimeSpan.FromMilliseconds((Int32)rnd.Next(500,3000))) .Select(i => { RandomValue = rnd.Next(300); return RandomValue; }); Server s = Server.Create("Default"); Microsoft.ComplexEventProcessing.Application a = s.CreateApplication("Rx SI Mischung"); var inputStream = interval.ToPointStream(a, evt => PointEvent.CreateInsert( System.DateTime.Now.ToLocalTime(), new { RandomValue = evt}), AdvanceTimeSettings.IncreasingStartTime, "Rx Sample"); var r = from evt in inputStream select new { runningVal = evt.RandomValue }; foreach (var x in r.ToPointEnumerable().Where(e => e.EventKind != EventKind.Cti)) { Console.WriteLine(x.Payload.ToString()); } This next version though uses the Reactive Extensions Only   var rnd = new Random(); var RandomValue = 0; Observable.Interval(TimeSpan.FromMilliseconds((Int32)rnd.Next(500, 3000))) .Select(i => { RandomValue = rnd.Next(300); return RandomValue; }).Subscribe(Console.WriteLine, () => Console.WriteLine("Completed")); Console.ReadKey();   These are very simple examples but both technologies allow us to do a lot more.  The ICEPObservable() design pattern was reintroduced in StreamInsight 1.1 and the more I use it the more I like it.  It is a very useful pattern when wanting to show StreamInsight samples as is the IEnumerable() pattern.

  • How to use SharpSVN to (quickly) check if a remote folder/file exists on the server

    - by Ziphnor
    Say i have a svn repository at https://www.mysvn.com/svn/. How can i use SharpSVN to figure out whether the remote folder https://www.mysvn.com/svn/a/b/c exists on the server? I need to do it an a way that allows me to tell the difference between a failed connection (ie server down) and the folder simply not having been created yet. Calling info on the full https://www.mysvn.com/svn/a/b/c path does not seem to give an exception that enables me to tell the difference between no repository at all and just a missing folder. I could list all files for https://www.mysvn.com/svn/ but the repository can easily be so big that this can take too long. Right now im doing an info on first the root url and then on the full url. If the root url fails i treat it as a server problem, but if it succeeds and the full url fails i assume its because part of the path hasnt been created on the server.

How do I do this? Is there a way to embed PHP in an article? If so, then I could just use $_GET["ReferenceCode"] to stick that parameter in the URL.

  • Help with Kohana 3 and a CRON

    I've set up a CRON to call a URL in Kohana 3. php /home/user/public_html/index.php my/route/in/bootstrap.php It seems to access the URL fine. However, I have received this error (send back in an email that my host sends per CRON) Undefined index: HTTP_HOST SYSPATH/classes/kohana/url.php [ 40 ] Source of url.php Which is in a Kohana system file. Is this because the CRON job is not sending HTTP headers? How would I fix this and get it to work (hopefully without hacking the core files). Or am I doing the CRON wrong?

  • Array variable initialization error in Java

  • Metro: Understanding the default.js File

    - by Stephen.Walther
    The goal of this blog entry is to describe — in painful detail — the contents of the default.js file in a Metro style application written with JavaScript. When you use Visual Studio to create a new Metro application then you get a default.js file automatically. The file is located in a folder named \js\default.js. The default.js file kicks off all of your custom JavaScript code. It is the main entry point to a Metro application. The default contents of the default.js file are included below: // For an introduction to the Blank template, see the following documentation: // http://go.microsoft.com/fwlink/?LinkId=232509 (function () { "use strict"; var app = WinJS.Application; app.onactivated = function (eventObject) { if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.launch) { if (eventObject.detail.previousExecutionState !== Windows.ApplicationModel.Activation.ApplicationExecutionState.terminated) { // TODO: This application has been newly launched. Initialize // your application here. } else { // TODO: This application has been reactivated from suspension. // Restore application state here. } WinJS.UI.processAll(); } }; app.oncheckpoint = function (eventObject) { // TODO: This application is about to be suspended. Save any state // that needs to persist across suspensions here. You might use the // WinJS.Application.sessionState object, which is automatically // saved and restored across suspension. If you need to complete an // asynchronous operation before your application is suspended, call // eventObject.setPromise(). }; app.start(); })(); There are several mysterious things happening in this file. The purpose of this blog entry is to dispel this mystery. Understanding the Module Pattern The first thing that you should notice about the default.js file is that the entire contents of this file are enclosed within a self-executing JavaScript function: (function () { ... })(); Metro applications written with JavaScript use something called the module pattern. The module pattern is a common pattern used in JavaScript applications to create private variables, objects, and methods. Anything that you create within the module is encapsulated within the module. Enclosing all of your custom code within a module prevents you from stomping on code from other libraries accidently. Your application might reference several JavaScript libraries and the JavaScript libraries might have variables, objects, or methods with the same names. By encapsulating your code in a module, you avoid overwriting variables, objects, or methods in the other libraries accidently. Enabling Strict Mode with “use strict” The first statement within the default.js module enables JavaScript strict mode: 'use strict'; Strict mode is a new feature of ECMAScript 5 (the latest standard for JavaScript) which enables you to make JavaScript more strict. For example, when strict mode is enabled, you cannot declare variables without using the var keyword. The following statement would result in an exception: hello = "world!"; When strict mode is enabled, this statement throws a ReferenceError. When strict mode is not enabled, a global variable is created which, most likely, is not what you want to happen. I’d rather get the exception instead of the unwanted global variable. The full specification for strict mode is contained in the ECMAScript 5 specification (look at Annex C): http://www.ecma-international.org/publications/files/ECMA-ST/ECMA-262.pdf Aliasing the WinJS.Application Object The next line of code in the default.js file is used to alias the WinJS.Application object: var app = WinJS.Application; This line of code enables you to use a short-hand syntax when referring to the WinJS.Application object: for example,  app.onactivated instead of WinJS.Application.onactivated. The WinJS.Application object  represents your running Metro application. Handling Application Events The default.js file contains an event handler for the WinJS.Application activated event: app.onactivated = function (eventObject) { if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.launch) { if (eventObject.detail.previousExecutionState !== Windows.ApplicationModel.Activation.ApplicationExecutionState.terminated) { // TODO: This application has been newly launched. Initialize // your application here. } else { // TODO: This application has been reactivated from suspension. // Restore application state here. } WinJS.UI.processAll(); } }; This WinJS.Application class supports the following events: · loaded – Happens after browser DOMContentLoaded event. After this event, the DOM is ready and you can access elements in a page. This event is raised before external images have been loaded. · activated – Triggered by the Windows.UI.WebUI.WebUIApplication activated event. After this event, the WinRT is ready. · ready – Happens after both loaded and activated events. · unloaded – Happens before application is unloaded. The following default.js file has been modified to capture each of these events and write a message to the Visual Studio JavaScript Console window: (function () { "use strict"; var app = WinJS.Application; WinJS.Application.onloaded = function (e) { console.log("Loaded"); }; WinJS.Application.onactivated = function (e) { console.log("Activated"); }; WinJS.Application.onready = function (e) { console.log("Ready"); } WinJS.Application.onunload = function (e) { console.log("Unload"); } app.start(); })(); When you execute the code above, a message is written to the Visual Studio JavaScript Console window when each event occurs with the exception of the Unload event (presumably because the console is not attached when that event is raised).   Handling Different Activation Contexts The code for the activated handler in the default.js file looks like this: app.onactivated = function (eventObject) { if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.launch) { if (eventObject.detail.previousExecutionState !== Windows.ApplicationModel.Activation.ApplicationExecutionState.terminated) { // TODO: This application has been newly launched. Initialize // your application here. } else { // TODO: This application has been reactivated from suspension. // Restore application state here. } WinJS.UI.processAll(); } }; Notice that the code contains a conditional which checks the Kind of the event (the value of e.detail.kind). The startup code is executed only when the activated event is triggered by a Launch event, The ActivationKind enumeration has the following values: · launch · search · shareTarget · file · protocol · fileOpenPicker · fileSavePicker · cacheFileUpdater · contactPicker · device · printTaskSettings · cameraSettings Metro style applications can be activated in different contexts. For example, a camera application can be activated when modifying camera settings. In that case, the ActivationKind would be CameraSettings. Because we want to execute our JavaScript code when our application first launches, we verify that the kind of the activation event is an ActivationKind.Launch event. There is a second conditional within the activated event handler which checks whether an application is being newly launched or whether the application is being resumed from a suspended state. When running a Metro application with Visual Studio, you can use Visual Studio to simulate different application execution states by taking advantage of the Debug toolbar and the new Debug Location toolbar.  Handling the checkpoint Event The default.js file also includes an event handler for the WinJS.Application checkpoint event: app.oncheckpoint = function (eventObject) { // TODO: This application is about to be suspended. Save any state // that needs to persist across suspensions here. You might use the // WinJS.Application.sessionState object, which is automatically // saved and restored across suspension. If you need to complete an // asynchronous operation before your application is suspended, call // eventObject.setPromise(). }; The checkpoint event is raised when your Metro application goes into a suspended state. The idea is that you can save your application data when your application is suspended and reload your application data when your application resumes. Starting the Application The final statement in the default.js file is the statement that gets everything going: app.start(); Events are queued up in a JavaScript array named eventQueue . Until you call the start() method, the events in the queue are not processed. If you don’t call the start() method then the Loaded, Activated, Ready, and Unloaded events are never raised. Summary The goal of this blog entry was to describe the contents of the default.js file which is the JavaScript file which you use to kick off your custom code in a Windows Metro style application written with JavaScript. In this blog entry, I discussed the module pattern, JavaScript strict mode, handling first chance exceptions, WinJS Application events, and activation contexts.

  • QWebView not loading external resources

    - by Nick
    Hi. I'm working on a kiosk web browser using Qt and PyQt4. QWebView seems to work quite well except for one quirk. If a URL fails to load for any reason, I want to redirect the user to a custom error page. I've done this using the loadFinished() signal to check the result, and change the URL to the custom page if necessary using QWebView.load(). However, any page I attempt to load here fails to pull in external resources like CSS or images. Using QWebView.load() to set the initial page at startup seems to work fine, and clicking any link on the custom error page will result in the destination page loading fine. It's just the error page that doesn't work. I'm really not sure where to go next. I've included the source for an app that will replicate the problem below. It takes a URL as a command line argument - a valid URL will display correctly, a bad URL (eg. DNS resolution fails) will redirect to Google, but with the logo missing. import sys from PyQt4 import QtGui, QtCore, QtWebKit class MyWebView(QtWebKit.QWebView): def __init__(self, parent=None): QtWebKit.QWebView.__init__(self, parent) self.resize(800, 600) self.load(QtCore.QUrl(sys.argv[1])) self.connect(self, QtCore.SIGNAL('loadFinished(bool)'), self.checkLoadResult) def checkLoadResult(self, result): if (result == False): self.load(QtCore.QUrl('http://google.com')) app = QtGui.QApplication(sys.argv) main = MyWebView() main.show() sys.exit(app.exec_()) If anyone could offer some advice it would be greatly appreciated.

  • Python urllib.urlopen IOError

    - by Michael
    So I have the following lines of code in a function sock = urllib.urlopen(url) html = sock.read() sock.close() and they work fine when I call the function by hand. However, when I call the function in a loop (using the same urls as earlier) I get the following error: > Traceback (most recent call last): File "./headlines.py", line 256, in <module> main(argv[1:]) File "./headlines.py", line 37, in main write_articles(headline, output_folder + "articles_" + term +"/") File "./headlines.py", line 232, in write_articles print get_blogs(headline, 5) File "/Users/michaelnussbaum08/Documents/College/Sophmore_Year/Quarter_2/Innovation/Headlines/_code/get_content.py", line 41, in get_blogs sock = urllib.urlopen(url) File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/urllib.py", line 87, in urlopen return opener.open(url) File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/urllib.py", line 203, in open return getattr(self, name)(url) File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/urllib.py", line 314, in open_http if not host: raise IOError, ('http error', 'no host given') IOError: [Errno http error] no host given Any ideas?
