  • Any reason not to use USE_ETAGS with CommonMiddleware in Django?

    - by allyourcode
    The only reason I can think of is that calculating ETag's might be expensive. If pages change very quickly, the browser's cache is likely to be invalidated by the ETag. In that case, calculating the ETag would be a waste of time. On the other hand, a giving a 304 response when possible minimizes the amount of time spent in transmission. What are some good guidelines for when ETag's are likely to be a net winner when implemented with Django's CommonMiddleware?

  • Codeigniter error logs show a 404 non-existing images directory...need to worry?

    - by user342199
    I've recently started logging my errors through codeIgniter. Since doing so, I have noticed a lot of 404 errors for directories that don't exist. For example: ERROR - 2010-05-15 21:06:26 -- 404 Page Not Found -- someController/images Where someController is, obviously, a controller. The problem is, there are no functions within that controller called images, nor are there any links to a directory by that name. Could this be that someone is trying to hack my site? If so, do I need to worry? If not, why is this happening? Thanks, and forgive the newby-ness.

  • 404 on custom post types after updating Wordpress to 3.7

    - by Chris
    Since I updated Wordpress from 3.6 to 3.7, I'm not able to visit the single-pages on my custom post types, then I get a 404 error. I thought this would be a rewrite_rules issue, so I've tried the following: -Go to the Permalink settings, click save (flush rewrites) -Manually deleted the rewrite_rules from the option table in the DB (I was desparate, and it seriously worked for me one time) -Re-check my .htaccess, but this is the exactly same as instructed on the permalink page -switched off the plugins I also tried switching the permalink to the "ugly" url (eg. ?page=35) and check if the articles worked, and they did! So I'm pretty sure it's a permalink issue. Now I rolled back to 3.6 again, but I of course want to upgrade in the near future (security etc.). A remarkable thing was that during the rollback I checked out a single page (notice that I didn't rolled back the database yet, only the files) and surprisingly they worked again. Any suggestions on how to solve this?

  • How do I ensure jQuery ajax call does not send a local copy of file?

    - by Tommy
    $.ajax({ type: 'GET', url: "string.txt", cache: false, success: function(str){ alert("Data is: "+ str); } }); In this example, string.txt is still sent to the cache (\Temporary Internet Files) How do I ensure that the file is not sent - read from the server only? Am I missing an option? I set cache to false but that does not block it from being sent to client. For example, ajax POST does not send a local copy..... Thanks

  • Browser removing + from request parameter

    - by Marquinio
    Hello everyone, I'm trying to pass an SQL query string from a Java Applet to Servlet as a parameter. Problem is that in Applet I have something say: sql=select * from p where(+p=1) The resulting sql parameter in the Servlet is sql=select * from p where(+p=1). So anyone knows how to prevent the browser from removing the + character from parameters? Is there a escape character? Thank you.

  • How to post data in PHP using file_get_contents?

    - by Paras Chopra
    I am using PHP's function file_get_contents() to fetch contents of a URL and then I process headers through the variable $http_response_header. Now the problem is that some of the URLs need some data to be posted to the URL (for example, login pages). How do I do that? I realize using stream_context I may be able to do that but I am not entirely clear. Thanks.

  • is it possible to continue a file upload after a browser has been quit?

    - by sprugman
    If a user starts uploading a file (in a web app), and they close their browser before the upload completes, what happens? My guess would be that the upload gets abandoned, and the server has some garbage cleaning mechanism that kicks in eventually, but I'm not sure. Any difference between servers or server languages? Any difference between quitting the browser and just closing a window?

  • Outputcache - how to determine optimal value for duration?

    - by Steve
    I read somewhere that for a high traffic site (I guess that is a murky term as well), 30 - 60 seconds is a good value. Obviously I could do a load test and vary the values, but I couldn't find any kind of documentation on this. Most samples have a minute, a couple of minutes. There's no recommended range. Is there something on msdn or anywhere that talks about this?

  • Why "Content-Length: 0" in POST requests?

    - by stesch
    A customer sometimes sends POST requests with Content-Length: 0 when submitting a form (10 to over 40 fields). We tested it with different browsers and from different locations but couldn't reproduce the error. The customer is using Internet Explorer 7 and a proxy. We asked them to let their system administrator see into the problem from their side. Running some tests without the proxy, etc.. In the meantime (half a year later and still no answer) I'm curious if somebody else knows of similar problems with a Content-Length: 0 request. Maybe from inside some Windows network with a special proxy for big companies. Is there a known problem with Internet Explorer 7? With a proxy system? The Windows network itself? Google only showed something in the context of NTLM (and such) authentication, but we aren't using this in the web application. Maybe it's in the way the proxy operates in the customer's network with Windows logins? (I'm no Windows expert. Just guessing.) I have no further information about the infrastructure.

  • How to customize JBoss AS7 404 page

    - by user23308
    I already created a custom 404 page inside my web app deployed in JBoss AS 7.1. So if my app is at fubar dot com :8080/Myapp and I go to fubar dot com :8080/Myapp/xyzzy, I get the custom error page (defined in the web app's web.xml file). However, when I go to fubar dot com :8080/xyzzy, JBoss displays the default 404 page which discloses that it's JBoss and which JBoss version. I need to replace this page in order to hide this information. Please advise.

  • Radio buttons + array elements

    - by Mark
    I have a form that can be dynamically duplicated (with JS) so that the user can enter as much data as he wants. This works great for text inputs, because I just leave the name attribute the same (ending with a []) and then when the values are posted, it just returns me an array. Now I just realized that this doesn't work so well for radio buttons, because the names actually need to be unique for each set. But from the data standpoint, each set only returns one value, so retrieving the data from the POST data wouldn't be a problem, it just screws up the functionality of my form. There's no way around this, is there? I'm just screwed and I can't use arrays?

  • HTML/JS: open other website without associated coockies

    - by Tim
    I have a web shop which sends my customers to a pretty popular website to redeem their just purchased product (at my site). However, I keep getting complaints that the product has been redeemed at the wrong account. Because the other website is that popular, it often appears that when the customers computer is shared by others the wrong account was logged in (automatically by a coockie). Now I'm wondering which steps I can take to prevent this from happening, since I don't have control over the other website (which does not make clear enough who's logged in). Is there some way to open another website without its coockies?

  • Mod_rewrite on all website images

    - by Esteve Camps
    I'm designing an image repository. I want to uncouple the filename from the image html link. For instance: image in filesystem is called images/items/12543.jpg HTML is <img src="images/car.jpg" /> Does anyone strongly discourages me to rewrite all image requests using PHP so when retrieving images/car.jpg, Apache really replies content from images/items/12543.jpg? I don't know if I may get performance problems.

  • Threading in client-server socket program - proxy sever

    - by crazyTechie
    I am trying to write a program that acts as a proxy server. Proxy server basically listens to a given port (7575) and sends the request to the server. As of now, I did not implement caching the response. The code looks like ServerSocket socket = new ServerSocket(7575); Socket clientSocket = socket.accept(); clientRequestHandler(clientSocket); I changed the above code as below: //calling the same clientRequestHandler method from inside another method. Socket clientSocket = socket.accept(); Thread serverThread = new Thread(new ConnectionHandler(client)); serverThread.start(); class ConnectionHandler implements Runnable { Socket clientSocket = null; ConnectionHandler(Socket client){ this.clientSocket = client; } @Override public void run () { try { PrxyServer.clientRequestHandler(clientSocket); } catch (Exception ex) { ex.printStackTrace(); } } } Using the code, I am able to open a webpage like google. However, if I open another web page even I completely receive the first response, I get connection reset by peer expection. 1. How can I handle this issue Can i use threading to handle different requests. Can someone give a reference where I look for example code that implements threading. Thanks. Thanks.

  • Sample code for POST + cookie?

    - by OverTheRainbow
    Hello, I've been googling for some VB.Net code to authenticate to a web server with the POST method, receive a session ID in a cookie, and then send this cookie along with all GET queries... but all I found is half-working code or C# code, ie. difficult to use for a VB.Net newbie. Would someone have some code handy or some pointer that I could use to get started? Thank you.
