  • Does using web services to expose a .NET DAL add security?

    - by Jonno
    Currently my employer deploys a web application over 3 servers. DB - No public route Web Service DAL - No public route Web Server - Public route The reason for this is the theory that if the web server is compromised, they don't arrive at the DB directly, but instead arrive at the DAL box. To my mind, as the DAL box and Web Sever box - both run windows/IIS - if the public box has been compromised, the same exploit would likely work on the DAL box - therefore I do not see this as a real security benefit. I would like to propose we remove the middle machine and allow the web server to connect directly to the database. Is this middle box really a benefit?

    - by AJM
    In my ASP.NET application I want to implement by data acess layer using the Entity framweok so I can use it as an ORM tool. But I dont want the rest of the application to care that I'm using this or be polluted by anything entity frameowrk specific. I cant seem to find anyone who is using the entity framework exclusively in their Data access layer so I'm keen to see any online examples of this/ experience people have.

  • Tornado Web & Persistent Connections

    - by Engrost
    How can I write Http server in TornadoWeb that will support persistent Connections. I mean will be able to receive many requests and answer to them without closing connection. How does it actually work in async? I just want to know how to write handler to handle persistent connection. How actually would it work? I have handler like that: class MainHandler(RequestHandler): count = 0 @asynchronous def post(self): #get header content type content_type = self.request.headers.get('Content-Type') if not content_type in ACCEPTED_CONTENT: raise HTTPError(403, 'Incorrect content type') text = self.request.body self.count += 1 command = CommandObject(text, self.count, callback = self.async_callback(self.on_response)) command.execute() def on_response(self, response): if response.error: raise HTTPError(500) body = response.body self.write(body) self.flush() execute calls callback when finishes. is my asumption right that with things that way post will be called many times and for one connection count will increase with each httprequest from client? but for each connection I will have separate count value?

The comments are stored in a different table from the stories. The code above does not return any values and doesn't show any errors. Could someone please help?

  • URL shortening: using inode as short name?

    - by Licky Lindsay
    The site I am working on wants to generate its own shortened URLs rather than rely on a third party like tinyurl or bit.ly. Obviously I could keep a running count new URLs as they are added to the site and use that to generate the short URLs. But I am trying to avoid that if possible since it seems like a lot of work just to make this one thing work. As the things that need short URLs are all real physical files on the webserver my current solution is to use their inode numbers as those are already generated for me ready to use and guaranteed to be unique. function short_name($file) { $ino = @fileinode($file); $s = base_convert($ino, 10, 36); return $s; } This seems to work. Question is, what can I do to make the short URL even shorter? On the system where this is being used, the inodes for newly added files are in a range that makes the function above return a string 7 characters long. Can I safely throw away some (half?) of the bits of the inode? And if so, should it be the high bits or the low bits? I thought of using the crc32 of the filename, but that actually makes my short names longer than using the inode. Would something like this have any risk of collisions? I've been able to get down to single digits by picking the right value of "$referencefile". function short_name($file) { $ino = @fileinode($file); // arbitrarily selected pre-existing file, // as all newer files will have higher inodes $ino = $ino - @fileinode($referencefile); $s = base_convert($ino, 10, 36); return $s; }

  • Client Web Browser Behavior When Handling 301 Redirect

    - by Jon Swanson
    The RFC seems to suggest that the client should permanently cache the response: http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html 10.3.2 301 Moved Permanently The requested resource has been assigned a new permanent URI and any future references to this resource SHOULD use one of the returned URIs. Clients with link editing capabilities ought to automatically re-link references to the Request-URI to one or more of the new references returned by the server, where possible. This response is cacheable unless indicated otherwise. The new permanent URI SHOULD be given by the Location field in the response. Unless the request method was HEAD, the entity of the response SHOULD contain a short hypertext note with a hyperlink to the new URI(s). If the 301 status code is received in response to a request other than GET or HEAD, the user agent MUST NOT automatically redirect the request unless it can be confirmed by the user, since this might change the conditions under which the request was issued. Note: When automatically redirecting a POST request after receiving a 301 status code, some existing HTTP/1.0 user agents will erroneously change it into a GET request. I'm having a hard time finding concrete browser documentation for any major browser that states how they handle these. I've started digging through the source code of firefox, but quickly got lost. Is the following scenario true for which (if any) browsers, and is there definitive documentation for either Firefox or IE that states as much?: First Time Around: 1.1: User enters link to site A, or clicks on a link directed at Site A 1.2: Browser interprets link at Site A, first time, no cache. Sends GET to Site A. 1.2: Site A responds with 301 Redirect to Site B 1.3: Browser sends GET to Site B. Any Subsequent Times Around: 2.2: User clicks on a link directed at Site A 2.2: Browser sees that, due to a past 301 redirect, Site A should now be Site B. 2.3: Without initiating any request whatsoever at Site A, browser initiates GET at Site B.

    - by Nitz
    Hey guys How to make software work like torrent work? Bcz always when i see that torrent software then i am really amazed by their sizes and what they do in that sizes? How they managed the download by parts and then all together as soon as u downloaded full part? and as soon as you had great speed then your download speed automatically goes up? How to make software which will work like torrent means peer-to-peer? how to make this kind of software which can download from different servers and managed to know each users download and upload? and how they have pretty small size? which tech. they have used in that kind of software? Sorry i had asked many question. I know how downloading is happening means peer-to-peer all that.. but i don't know how they have built that kind of thing?

  • WS Libs: com.sun.xml vs javax.xml

    - by Zilvinas
    There are identical classes of java WebServices API & IMPL in those packages groups, only package names are different. http://mvnrepository.com/artifact/javax.xml http://mvnrepository.com/artifact/com.sun.xml Which ones should I use in my code? I would prefer NON-com.sun.* as per java conventions, but still my dependencies ( e.g. Spring ) are using implementations from com.sun.* OR I can't find an implementation package in javax.xml Does anyone have any experience on this?

  • What is a good approach to preloading data?

    - by Bob Horn
    Are there best practices out there for loading data into a database, to be used with a new installation of an application? For example, for application foo to run, it needs some basic data before it can even be started. I've used a couple options in the past: TSQL for every row that needs to be preloaded: IF NOT EXISTS (SELECT * FROM Master.Site WHERE Name = @SiteName) INSERT INTO [Master].[Site] ([EnterpriseID], [Name], [LastModifiedTime], [LastModifiedUser]) VALUES (@EnterpriseId, @SiteName, GETDATE(), @LastModifiedUser) Another option is a spreadsheet. Each tab represents a table, and data is entered into the spreadsheet as we realize we need it. Then, a program can read this spreadsheet and populate the DB. There are complicating factors, including the relationships between tables. So, it's not as simple as loading tables by themselves. For example, if we create Security.Member rows, then we want to add those members to Security.Role, we need a way of maintaining that relationship. Another factor is that not all databases will be missing this data. Some locations will already have most of the data, and others (that may be new locations around the world), will start from scratch. Any ideas are appreciated.

  • I have a bunch of divs floated left, lined up in columns with different heights. They dont create a

    - by Roeland
    Hey guys, I am trying to create a grid like system with div's with content floated left. The problem is that the height of each div is not static since the content is different in each one. Since the height is different.. things get outta whack if one is taller then another in one row. Is there some sort of css way or js (prefer javascript) way to get around this. I really want to avoid setting large heights on the divs to get them to line up. You can see the example here: http://www.foreclosurejournalinc.com/index.php?option=com_hotproperty&view=type&id=1

  • Using SalesForce's Web Service to create and set the type of a Task

    - by Alan Williamson
    I am successfully creating a Task using the SalesForce API SOAP API through Java. However, my problem is that I can't seem to set the Type of it. They all default to "Call" but I really want them to be "Email". Can someone point me in the direction of where I can do this? I think it is to do with RecordTypeMapping, but i am somewhat confused as to how to use this in my Java code to look up the particular one for Task type. I feel I have got so close with this. I have the correct WSDL that is giving me the extra method on the Task.java class, but no matter what I pass in, it dies. This doesn't seem to be a huge ask, yet i am perplexed as to which dots to join to get it to work Any help would be appreciated. thanks

  • Breeze Expand not working on WebAPI with EF

    - by Rodney
    I have published a WebAPI service which returns a list of items. I am implementing Breeze and have managed to get it basically working with filtering/sorting. However, the Expand is not working. http://www.ftter.com/desktopmodules/framework/api/dare/dares/?$filter=DareId%20eq%2010&expand%20eq%20ToUser You can see the ToUserId ForeignKey in the response above, but the ToUser properties are NULL (the user definitely exists) You can see the ToUser EF navigation property in the metadata. When I use .Include on the server side I can populate it with EF, but I don't want to do this. [HttpGet] [Queryable(AllowedQueryOptions = AllowedQueryOptions.All)] public HttpResponseMessage Dares() { var response = Request.CreateResponse(HttpStatusCode.OK, (IQueryable<Dare>)contextProvider.Context.Dares); return ControllerUtilities.GetResponseWithCorsHeader(response); } and here is the generated class from my EF model (using Database First) public partial class Dare { public int DareId { get; set; } public int ToUserId { get; set; } public virtual User ToUser { get; set; } }

  • CSS box around box technique

    - by webzide
    Dear Experts, I was trying to make an CSS division box with content in it as well as a border around it. Instead of using the box-border technique, I was trying out a new box to box technique instead. <html> <head> <style type="text/css"> #outer{ height: 20px; width: 20px; background-color:#233D78; } #inner{ height:18px; width: 18px; background-color: #FFF; font-size: 1em; text-align:center; font-family:'Bookman Old Style', serif; padding: 0px; margin-top: 1px; margin-right:auto; margin-left:auto; margin-bottom:1px; vertical-align:middle; } </style> </head> <body> <div id="outer"><div id="inner">TEXT</div></div> </body> </html> Somehow the borders are just not showing up right with FireFox. I tried everything. Setting up the Paddings of both boxes, margin, and messing around with the width. TO be honest, it took me around 30min to do this and I still can't get it right :( I know that a way to achieve the same result would be setting up a border around just one box. But I just wanna learn this box around box background-color technique. THanks in advance

  • Weird problem: IE8 user can't authenticate with web service

    - by NovaJoe
    I have an asp.net app. It has a page that requires authentication. The authenticated user can view the page because he/she is authenticated. The page makes a jQuery Ajax call to a WCF service. The WCF service checks that the user is authenticated via HttpContext. I have a user that is using WinXP and IE8. This user can authenticate to the page, but when the Ajax call is made from the page to the wb service, the user recieves my "session not authenticated" message on the page, generated by the service and displayed on the page. When I use the same OS/browser combo, the page and service work just fine, as expected; no errors. What option in this user's IE settings would cause this behavior?
