• PHP website Optimization

  - by ana

  I have a high traffic website and I need make sure my site is fast enough to display my pages to everyone rapidly. I searched on Google many articles about speed and optimization and here's what I found: Cache the page Save it to the disk Caching the page in memory: This is very fast but if I need to change the content of my page I have to remove it from cache and then re-save the file on the disk. Save it to disk This is very easy to maintain but every time the page is accessed I have to read on the disk. Which method should I go with? Thanks

• Static variables and long running thread on IIS 7.5

  - by Dmitry

  Hello people. Help me solve next problem. I have ASP .NET MVC2 application. I run it on IIS 7.5. In one page user clicks button and handler for this button sends request to server (jquery.ajax). At server action in controller starts new thread (it makes long time import): var thread = new Thread(RefreshCitiesInDatabase); thread.Start(); State of import is available in static variable. New thread changes value of variable in the begin of work. User can check state of import too with the help of this variable, which is used in view. And user sees import's state. When I start this function few minutes everything is okey. On page I see right state of import, quantity of imported records is changed, I see changes in logs. But after few minutes begin troubles. When I refresh page with import state sometimes I see that import is okey but sometimes I see page with default values about import (like application is just started), but after that again I can see page with normal import's state. I tried to attach Visual Studio to IIS process and debug application. But when request comes to controller sometimes static variables have right values and sometimes they have default values (static int has 0, static string has "" etc.). Tell me what I do wrong. May be I must start additional thread in other way? Thanks in advance, Dmitry

• How to open window pop-up from Silverlight Out-of-Browser?

  - by Jeaffrey Gilbert

  I need to open window pop-up from Silverlight Out-of-Browser application. I've added parameter <param name="enablehtmlaccess" value="true" /> in Index.html, but executing this from code behind: HtmlPage.Window.Navigate(new Uri(myUrl), "_blank", myFeatures); still returns error: Silverlight OOB Error: The DOM/scripting bridge is disabled. I've read about this post, does it mean that I can't open pop-up from OOB? Why I need to do this, because actually I've shown the HTML page in OOB Silverlight by WebBrowser control within ChildWindow but when I click an anchor in HTML page, which linked to _blank page, it jumps to my default browser. It doesn't meet the requirement, except launch that HTML index page also in default browser at the first time, triggered from button control in OOB Silverlight. Is that possible? Please advice, thanks.

• Scala Lift - Robust method to protect files from hotlinking

  - by sirjamm

  I'm attempting to implement a way to stop hotlinking and/or un-authorised access to resources within my app. The method I'm trying to add is something I've used before in PHP apps. Basically a session is set when the page is first called. The images are added to the page via the image tag with the session value as a parameter: <img src="/files/image/[handle]?session=12345" /> When the image is requested the script checks to see if the session is set and matches the provided value. If the condition is not met the serving page returns null. Right at the end to the code I unset the session so further requests from outside the scope of the page will return null. What would be the best implementation of this method within the lift framework? Thanks in advance for any help, much appreciated :)

• Website Sitemaps and <priority>, is it working?

  - by Mike Gleason jr Couturier

  Hi, My "Privacy Policy" page is seen more important by Google than other really more important pages on my website. I'm currently creating a script to generate a sitemap, should I bother with the priority? How do you effectively assign priorities to pages? I consider one of my page important but the page have less content than another one less important to my eyes... but maybe Google bot will see it the other way around. If my degree of "importantness" differs from the one of Google, will I get penalized on the ranking for a particular page? Thank you for sharing your black art with us :P

• Dynamically load .asmx web-service

  - by Tierney

  I have an .aspx page that can perform a number of functions. The type of function is determined at run-time depending on which button the user clicks. This makes makes a web-service call to an .asmx method. The web-service call returns html and javascript which then become part of the original page. This new content has javascript events attached to button clicks, data validation etc. In turn these events then call their own web-service methods in another .asmx file. The main page does not know about these other .asmx files when the page loads. So, is there any way of dynamically loading these .asmx files on demand?

• login connection problem using SimpleTest

  - by Cedric

  Hi everyone. I am using SimpleBrowser from SimpleTest (http://www.simpletest.org) to login a webmin (http://www.webmin.com/). This login uses https. I've tried two different ways, both fail. $browser = new SimpleBrowser(); $browser->useCookies(); $browser->useFrames(); //echoes the login page, where it should echo the landing page from a logged user echo $browser->post('https://address/','user=User&pass=Secret')); And also : $browser = new SimpleBrowser(); $browser->useCookies(); $browser->useFrames(); $browser->get('https://address/'); $browser->setField('user', 'User'); $browser->setField('pass', 'Secret'); //echoes the login page, where it should echo the landing page from a logged user echo $browser->clickSubmit('Login'); Do you have any clue why it doesn't work ?

• How to float a <div> echoed in the footer over a <div> located elsewhere (PHP/jQuery/HTML/CSS)

  - by PlasmaFlux

  Hello All! I'm embarking on a major project, but am stuck on a tiny issue at the very start. I'll try to be as concise as possible. I have a PHP script that will be echoing into the footer of the page (the last stuff before a bunch of s containing visible buttons and s containing hidden dialog boxes. The plan is to have the buttons float in the upper-right corner of corresponding s in the main content area of the page. i.e. - button-1 echoed into the footer will float in the corner of content-box-1, and will be tied to the hidden 'dialog-1'. I'll be using jQuery and jQuery UI Dialog throughout the page(s). I'm not sure if that's particularly relevant to this question, but thought it worth mentioning just in case. So my question, put simply, is how do I echo a Button 1 into the footer with PHP, but have it float in the upper-right corner (with maybe 5px margin) of Content 1 is full of content? A picture says a thousand words: As shown above, I want the little blue gear button things in the corner of content pieces, locked and loaded with hidden s containing dialog boxes. Again, the catch is that all buttons and hidden divs will be the very last items echoed into the page footer. I've found plenty of info on how to float divs on top of divs, but all the examples I saw showed the s in close proximity to each other in the page source; not with a hundred lines of source code between the two s I'm not sure if the solution is pure CSS, pure jQuery/jQueryUI or a combination of the two. Any advice will be much appreciated. Thanks!

• Drupal 5 Search not working on 404 pages.

  - by easement

  I have a <?php print $search_box; ?> in my page.tpl.php page. On pages that exist, the search works, but on 404 pages, it does not. I saw some bugs/patches threads over at drupal.org for D6.15, but none of them seem to work according to the thread and they weren't really relevant to D5.x I have a theory that the because the <?php print $search_box; ?> creates a form with an action to itself(a non-existant page), it'll get the 404. Has anyone run up against this? If so, how did you fix it? One theory I has was to somehow tap into the form and always make the action="/" (front page) which would always exist. If this is a good idea, how does one go about tapping into the FormAPI and overwriting the action? Is it a preprocess function?

• eclise java internal webbrowser progress listener?

  - by deepthinker121

  Hi All, I need to open an internal web browser from a custom eclipse wizard I have created - and so I am using IWebBrowser webBrowser = browser.createBrowser (IWorkbenchBrowserSupport.LOCATION_BAR | IWorkbenchBrowserSupport.AS_EDITOR | IWorkbenchBrowserSupport.NAVIGATION_BAR | IWorkbenchBrowserSupport.STATUS, null,"TestBrowser", "TestBrowser"); URL url = new URL("http://localhost:8080/app"); webBrowser.openURL(url); Now the problem is - the openURL needs time to complete as it tries to load a page for a webapp and as I am not able to get the progress of the 'load page' operation of the URL - my wizard progressmonitor completes before the URL can be completely loaded . Is there any way to get the status of the page load operation - (to check if its complete or it failed) or add a listener to indicate completion of page load? It is okay for me to use some other implementations of internal web browsers - so please suggest some other approach we cannot add a listener to IWebBrowser.. Thanks for ur help !!

• Cache for everybody except staff members.

  - by Oli

  I have a django site where I want to stick an "admin bar" along the top of every non-admin page for staff members. It would contain useful things like page editing tools, etc. The problem comes from me using the @cache_page decorator on lots of pages. If a normal user hits a page, the cached version comes up without the admin bar (even for admin users) and if an admin hits the page first, normal users see the admin bar. I could tediously step through the templates, adding regional cache blocks but there are a lot of templates, and life is altogether too short. Ideally, there would be a way of telling the caching to ignore cache get/set requests from admin users... But I don't know how to best implement that. How would you tackle this problem?

• How can I test caching and cache busting?

  - by Nathan Long

  In PHP, I'm trying to steal a page from the Rails playbook (see 'Using Asset Timestamps' here): By default, Rails appends assets' timestamps to all asset paths. This allows you to set a cache-expiration date for the asset far into the future, but still be able to instantly invalidate it by simply updating the file (and hence updating the timestamp, which then updates the URL as the timestamp is part of that, which in turn busts the cache). It‘s the responsibility of the web server you use to set the far-future expiration date on cache assets that you need to take advantage of this feature. Here‘s an example for Apache: # Asset Expiration ExpiresActive On <FilesMatch "\.(ico|gif|jpe?g|png|js|css)$"> ExpiresDefault "access plus 1 year" </FilesMatch> If you look at a the source for a Rails page, you'll see what they mean: the path to a stylesheet might be "/stylesheets/scaffold.css?1268228124", where the numbers at the end are the timestamp when the file was last updated. So it should work like this: The browser says 'give me this page' The server says 'here, and by the way, this stylesheet called scaffold.css?1268228124 can be cached for a year - it's not gonna change.' On reloads, the browser says 'I'm not asking for that css file, because my local copy is still good.' A month later, you edit and save the file, which changes the timestamp, which means that the file is no longer called scaffold.css?1268228124 because the numbers change. When the browser sees that, it says 'I've never seen that file! Give me a copy, please.' The cache is 'busted.' I think that's brilliant. So I wrote a function that spits out stylesheet and javascript tags with timestamps appended to the file names, and I configured Apache with the statement above. Now: how do I tell if the caching and cache busting are working? I'm checking my pages with two plugins for Firebug: Yslow and Google Page Speed. Both seem to say that my files are caching: "Add expires headers" in Yslow and "leverage browser caching" in Page Speed are both checked. But when I look at the Page Speed Activity, I see a lot of requests and waiting and no 'cache hits'. If I change my stylesheet and reload, I do see the change immediately. But I don't know if that's because the browser never cached in the first place or because the cache is busted. How can I tell?

• Manually start session with specific id / transitioning session cookie between domains

  - by deceze

  My host requires me to use a different domain for SSL secured access (shared SSL), so I need to transition the user session between two domains. One part of the page lives at http://example.com, while the SSL'd part is at https://example.hosting.com. As such I can't set a domain-spanning cookie. What I'm trying to do is to transition the session id over and re-set the cookie like this: http://example.com/normal/page, user clicks link to secure area and goes to: http://example.com/secure/page, which causes a redirect to: https://example.hosting.com/secure/page?sess=ikub..., which resurrects the session and sets a new cookie valid for the domain, then redirects to: https://example.hosting.com/secure/page This works up to the point where the session should be resurrected. I'm doing: function beforeFilter() { ... $this->Session->id($_GET['sess']); $this->Session->activate(); ... } As far as I can tell this should start the session with the given ID. It actually generates a new session ID though and this session is empty, the data is not restored. This is on CakePHP 1.2.4. Do I need to do something else, or is there a better way to do what I'm trying to do?

• What would the conditional statement be to filter these inputs?

  - by dmanexe

  I have a page with a form, and on the form are a bunch of input check boxes. In the following page, there's the following code to process the inputs from the page before (which are set as an ID). <? $field = $this->input->post('measure',true); $totals = array(); foreach($field as $value): $query = $this->db->get_where('items', array('id' => $value['input']))->row(); $totals[] = $query->price; ?> #HTML for displaying estimate output here <?php endforeach; ?> How would I have the loop run conditionally only if there was a check on the input on the page before?

I plan to achieve this by putting [pFirstRun] = False as my first WHERE condition with the parameter pFirstRun tied to the value isPostBack. How do I achieve this? Alternatively, is there a better way to achieve this goal?

• service not defined when precompiling a web app with AJAX-enabled WCF Service

  I created a web application in which one .aspx page calls an AJAX-enabled WCF service (created with Visual Studio 2008 Add New Item - AJAX-enabled WCF Service). when I test the application in Visual Studio, it works and the page can call the service from Javascript but when I "publish" (code precompilation using Visual Studio) it to the local IIS Server, I get an error : "service ThunServ is undefined" in my .html page. I've been spending quite a time to solve this problem but to no avail. Attarea.

• Javascript performance issue

  - by Daniel

  Hello, I've built a top menu based on superfish, but the amount of displayed items in the menu is huge. And there is also alot of jquery on the top menu. Now to the problem, everytime I load any page that has the menu, the browser(ie7) feels like it looks it locks it self for about 1-2 seconds while the page is being loaded. I'm sure that the top menu is the issue, and I would like to improve the performance of the page.(besides removing the menu and removing the menu items) I've used firebug to see which calls take most of the times, and I the calls are standard jquery or superfish. The top menu is a ascx control. Are they any good ways to let the page load first and the menu later or any other goods ideas to improve the performance?

• Chromium always starts as floating in awesome.wm

  - by xhochy

  I'm using awesome as window manager for a small surf&info terminal. Chromium is started directly after login on the first workspace and should be displayed fullscreen. I've set the layout of all workspaces to awful.layout.suit.max and followed Awesome FAQ so that Chromium and all other (automatically) started programs will be shown on the right workspace. All programs except Chromium will start correctly in fullscreen mode. I tried { rule = { class = "chromium-browser" }, properties = {floating = false, tag = tags[1][1]}} and { rule = { class = "chromium-browser" }, properties = {tag = tags[1][1]}} but Chromium will always start in floating mode. This is a bit annoying as you still see awesome's panel at the top.

• Rails - how can I capture the URL that directed to the current action in my app?

  - by sa125

  Hi - I need to see what page a request came from in my controller so I could be able to redirect back to it. For example, if I'm on a page showing a specific product (say /products/1) and it has a link to its vendor (/vendors/12), I want to be able to detect inside the vendors_controller that I came to that page from /products/1. Is there a simple way in Rails to achieve this, so that I could access it via params or session? thanks.

• Google Analytics - Events versus Pageviews, can you compare them?

  - by Aart Nicolai

  Hi, A mortgage page on our website is accesible by multiple links on one page. In order to determine which of the links on that same page has been clicked on, I use event tracking. All events for these links are being stored under the category: "mortgage" When I look at the total number of pageviews for this mortgage page and the total number of events for the event category "mortgage", the number of pageviews is 10%-20% higher. My questions are: Can I compare pageviews and events? If not, why not? Thanks, Aart Nicolai (funda.nl)

• 301 Redirecting URLs based on GET variables in .htaccess

  - by technicalbloke

  I have a few messy old URLs like... http://www.example.com/bunch.of/unneeded/crap?opendocument&part=1 http://www.example.com/bunch.of/unneeded/crap?opendocument&part=2 ...that I want to redirect to the newer, cleaner form... http://www.example.com/page.php/welcome http://www.example.com/page.php/prices I understand I can redirect one page to another with a simple redirect i.e. Redirect 301 /bunch.of/unneeded/crap http://www.example.com/page.php But the source page doesn't change, only it's GET vars. I can't figure out how to base the redirect on the value of these GET variables. Can anybody help pls!? I'm fairly handy with the old regexes so I can have a pop at using mod-rewrite if I have to but I'm not clear on the syntax for rewriting GET vars and I'd prefer to avoid the performance hit and use the cleaner Redirect directive. Is there a way? and if not can anyone clue me in as to the right mod-rewrite syntax pls? Cheers, Roger.
