• expiring image assets referenced from stylesheets

  - by crankharder

  So rails appends timestamps to CSS, JS and image files: image_tag 'foo.png' => <img src="foo.png?123123123123' /> # or somethin like that ...which is really useful for doing far-future expiration, etc. with Apache's help. But what about images referenced from stylesheets? They don't get an appended timestamp. So it seems to me that it's entirely possible to update one of those images, redeploy, and then not see the file change because the browser doesn't think it's been updated. Unless I'm missing something. If I'm not, is there a decent solution to this problem?

• Get the size of a Silverlight window

  - by Aidenn

  Hey! I'm creating a Silverlight 4 Out Of Browser application. I have my MainPage that will be the "central" application. I want to be able to display another Control next to the MainPage, by using a Popup and I want it to be displayed right next to the MainPage. How can I get the coordinates of the upper right corner of the MainPage at each moment? (Beware that this MainPage can be moved all over the screen and hence I will need to dynamically get the corner coordinates, in order to display my popup right next to the main window). Any thoughts on this? Thank you!! PS: the code is in C# :-)

• Are your redirects HTTP compliant (absolute URI)?

  - by webbiedave

  In the Hypertext Transfer Protocol 1.1 spec, it states for the Location header: The field value consists of a single absolute URI. Location = "Location" ":" absoluteURI An example is: Location: http://www.w3.org/pub/WWW/People.html I have coded many an app that doesn't include the scheme and domain (i.e., /thankyou/) and every browser I've ever tested with redirects correctly. I'm wondering if it's imperative to go back and change all my redirect code or just ignore this part of the spec. Have many of you produced code that doesn't comply and will you go back and change it? Or will you just trust that clients will continue to resolve them well into the future? (going forward I will certainly adhere to this)

• In QT 4.6 w/ Webkit: How to handle popup window requests (WebView::createWindow)?

  - by CM

  Hi all, I'm new to QT and have been trying to create a test browser. What I'm trying to do now is to handle js-based popup requests. After reading the QT documentation, I learned that I need to re-implement the QWebView::createWindow method to do just that. Now I've re-implemented this method, but it seems to be not called when I try to click a link that triggers a popup window. Can any one help me? Do I need to subclass both the WebView and WebPage classes? If so, how do I do that? I'm quite new to QT and I've done tons of searches and found nothing. Thank you all in advance for any hint and advice!

• how to handle large dataset like sproutcore

  - by Nik

  Hello all, I really don't have any substantial code to show here, actually, that's kinda why I am writing: I looked at the SproutCore demo, especially the Collection demo, on http://demo.sproutcore.com/sample_controls/, and am amazed by its loading 200,000 records to the page so easily. I tried using Rails to provide 200,000 records and in a completely blank HTML page with <% @projects.each do |p| % <%= p.title % <% end % that freezes the browser for seconds on my m1530 laptop with 4gb ram and t7700 256gb ssd. Yet the sproutcore demo does not freeze and takes less than 3 seconds to load. What do you think the one technique they are using to enable this is? Thanks!

Does anyone know how to fix this problem or should i switch to Apache?

• background semitransparent div

  - by plasticrabbit

  I want to show some dialog (absolute positioned div), and I want to show it above semitransparent 100% div, so everything on background will be dimmed. I have managed it by <div class='transpBox'></div> .transparentBox { position: absolute; top: 0px; left: 0px; width: 100%; height: 100%; background-color: #white; opacity: 0.9; z-index: 499; } This is all right, but when dialog height is more than browser height and you scroll down, you see that transparent div is not in full screen. What is proper way to make such thing?

• Running CodeIgniter cron on localhost

  - by stef

  I'm trying to get a cron job to run every 5 min on my localhost. Using the Cronnix app I entered the following command 0,5 * * * * root curl http://localhost:8888/site/ > /dev/null The script runs fine when I visit http://localhost:8888/site/ in my browser. I've read some stuff about getting CI to run on Cron, using wget and various other options but none make a lot of sense. In another SO post I found the following command wget -O - -q -t 1 http://www.example.com/cron/run What is the "-O - -q -t 1" syntax exactly? Are there other options?

• HTML5 localStorage for assets (stylesheets, JavaScript, images etc)

  - by Sam

  To save both client download time and network usage, is it possible to use the localStorage feature of HTML5 to store contents of linked stylesheets, javascript files and binary data (e.g. images), rather than hitting the server each time? Would that just complicate things - since I assume you would have to add the linked asset via JavaScript rather than just a script or link element, breaking the page for those without JavaScript enabled)? Unless you can parse the content (using HEAD requested to check last modified date and other headers) before the browser downloads it. Or best just to stick with 304 Not Modified and eTag headers?

• How to use a self-signed SSL certificate when developing with Trigger.io?

  - by user610345

  Our backend is in rails, and for several reasons the development environment has to be run with rails using a self-signed SSL certificate. This works fine on the desktop after manually trusting the certificate. Using Trigger.io, we're developing a mobile application targeting iOS from the same backend. It would be ideal for us to be able to run the rails server with SSL (so we can compare the browser output) and still have the iOS simulator connect properly without complaining about invalid certs. Production is using a proper ssl-cert, but what's the best way to set up the simulator?

• HTML not updating?

  - by Tommy

  I have a CGI application written in C. When I POST delete data to the app from the html form, the action is correctly executed on the server but the page does not refresh after the POST. It does flicker, but displays the non-updated page. I then have to hit the browsers refresh to see the correct html page. Is this the web server? Javascript? or just a browser setting? (I am using GoAhead web server, cgi app in C, javascript, html and Fire Fox.) Any help is appreciated.

• Which Java Web Framework allows Cross-Domain Javascripting (http proxy) ?

  - by snsd

  So just a quick intro, I am starting to explore Vaadin, and it's absolutely perfect. Previously, I was juggling PHP, Perl, Ruby, and Jquery for designing rich client web application. It didn't work out too well, as I've burnt out from trying to fix cross browser issues (aka get-it-to-work-on-IE-damn-it), handling server-side, client-side, and building a robust communication between the two tier had lot of code not related to application logic....by the time I was burnt out, only tiny bit of application logic was implemented. Vaadin seems like the answer to my problem as it only requires Java and built on top of GWT. However, I am curious how I can incorporate Cross-Domain Javascripting ? Back in LAMP environment, I had a CGI proxy script that loaded external URL, and injected JS into the proxy-loaded page. I used the CGI proxy script, as it rendered Javascript of the external URL well. Is there a class or package for Java or a specific Java web framework similiar to Vaadin that makes this possible ? Thank you.

• Sequencing ajax requests

  - by Scott Evernden

  I find I sometimes need to iterate some collection and make an ajax call for each element. I want each call to return before moving to the next element so that I don't blast the server with requests - which often leads to other issues. And I don't want to set async to false and freeze the browser. Usually this involves setting up some kind of iterator context that i step thru upon each success callback. I think there must be a cleaner simpler way? Does anyone have a clever design pattern for how to neatly work thru a collection making ajax calls for each item?

• Neural network input data, cartesian plane x/y coordinates, correlate with Handwriting.

  - by Sam

  I very curious about making a handwriting recognition application in a web browser. Users draw a letter, ajax sends the data to the server, neural network finds the closest match, and returns results. So if you draw an a, the first result should be an a, then o, then e, something like that. I'm don't know much about neural networks. What kinda data would I need to pass to the NN. Could it be an array of the x/y coordinates where the user has drawn on a pad. Or what type of data is the neural network expecting or would produce the best results for handwriting?

• Browsing to Subversion repository location indicated in Apache conf file

  - by sonrael

  I have Subversion 1.6.6 and Apache 2.2.14 installed and working. I have made the following changes to the Apache httpd.conf file: #Uncommented by me for Subversion installation LoadModule dav_module modules/mod_dav.so LoadModule dav_fs_module modules/mod_dav_fs.so #Added by me for subversion installation LoadModule dav_svn_module modules/mod_dav_svn.so LoadModule authz_svn_module modules/mod_authz_svn.so < Location /svn DAV svn SVNPath C:\Users\RED\Repositories < /Location ...When I navigate to localhost Apache is working properly, but if I try to go to localhost/svn the browser just hangs waiting for a response from the server. What is supposed to happen here? Does it have to do with the fact that I'm behind a wireless router on a dynamic IP address (although I can access localhost no problem so...)? As you can see I'm on windows (Vista)

• Strange Rendering in Firefox

  - by Alex

  I've just noticed when loading my client's page (http://habbopfm.com/) in Firefox, that it renders what looks like a rectangle is pushed down a few pixels. It's difficult to describe, but imagine you took a screenshot of the page, opened it in Photoshop, selected a rectangle and moved it down a bit. IE and Safari don't appear to do this - I'm assuming this is a browser glitch, not a problem with the code. Can anyone confirm what causes this? Below is a screenshot taken of the issue: http://habbopfm.com/problem.png One other thing is that it only does this once the page has finished loading. While it is loading, it looks fine.

• Problem with displaying my Image..

  - by Josh

  Here is my full problem so if anyone has any ideas or can offer some help, please let me know. I have a Website that will generate a Report and this Report takes some time to create. There is a MyReport.ASPX file that has a form1, Image1, and a ReportViewer control. There is also a MyReport.cs file that has C# code to generated a HTMLText string that the ReportViewer control will display. When I pull the Website up in the browser, the MyReport.cs file creates the Report before MyReport.ASPX ever gets called so my Image1 (which I need to display while the Report is being created) never gets displayed until AFTER the Report is created and displayed. What do you suggest I do here? If I did not supply enough information, please let me know what else you need to know and I will gladly post it. Thanks,

• how to verify that an old session is really destroyed?

  - by jodeci

  Um, this might sound a bit weird. We were having some problems with a specific browser under a very specific condition, and finally narrowed down the problem to the fact that we were not properly destroying the old sessions after doing session_regenerate_id(). I believe I have solved this problem by doing session_regenerate_id(true) now, but how does one verify that the previous sessions really do not exist any more? Someone suggested cURL but I cannot find my way around their docs. Sadly(?) the boss does not take 'it just works' for an answer so I'd really appreciate any advice!

• Crossplatform development for iPhone & Android

  - by LeonixSolutions

  As far as I can see there doesn't seem to any mature environment for crossplatform development for iPhone & Android slate (but feel free to correct me). I don't know Ipad, I must admit. Any reason why plain Java wouldn't cut it? (maybe underlying things like database (I am not too concerned with hardware)) I am thinking to try to make everything browser based, although that won't get around the d/b & h/w issues, unless there is JS framework that does so. Any advice?

• file_get_contents not displaying any data

  - by Lance

  I'm doing $info = file_get_contents('http://USERNAME:[email protected]/v2/sales?client_key=CLIENT_KEY'); $info returns nothing. However, when I put the URL into my browser, JSON appears. I tried using cURL without any luck. $data = array('client_key' => 'CLIENT_KEY'); $link = "http://api.appfigures.com/v2/sales"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $link); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_POST, count($data)); curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data)); curl_setopt($ch, CURLOPT_USERPWD, "username:password"); curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC); $jsonData = curl_exec($ch); curl_close($ch); print_r($jsonData); Thanks

  I have a setup lets say like follows: <div id="nav"> <div id="innernav"> //With dynamic content here. </div> </div> I am running a script that sizes #nav to the size of the browser window in height.

• Cross Domain Cookies Problem (ASP.NET)

  - by Laserson

  Hi guys, i have a problem with cross-domain cookies. I read a lot of documentation about sharing cookies between subdomains. The main idea of all articles is set Domain property to something like ".mydomain.com". I've created two domains on local IIS server - test1.local.boo and test2.local.boo. They works great and visible with browser. I have the following code: Site test1 - Writes cookie: HttpCookie myCookie = new HttpCookie("TestCookie"); myCookie.Domain = ".local.boo"; myCookie["msg"] = "Welcome from Cookie"; Response.Cookies.Add(myCookie); Site test2 - Reads cookie: HttpCookie cookie = Request.Cookies["TestCookie"]; if (cookie != null) { Response.Write(cookie["msg"]); } else { Response.Write("FAILED"); } This code always shows FAILED message. So it means that second site can't read cookie from the same subdomain. Where is my mistake??

  - by govardhan

  We have two applications. One application in .asp and second application in java. we want to build interface for universal authentication, so that one can access the other application once signed into one application. Both applications are using SQL database, but one is written in .ASP hosted on Windows server while the other is in JAVA hosted on a Linux server. The applications are currently resided on two different servers. requirements: 1)The end user are most likely to access the applications through .ASP first, then reach the 2nd application more like "back office" management system. 2)he JAVA application currently works well with IE web browser, but not very smooth with other browsers such as Firefox. Would like to make the application to be more compatible with other browsers. Please help me, its very important to me. Thanks in advance!
