  • Creating an API for an ASP.NET MVC site with rate-limiting and caching

    - by Maxim Z.
    Recently, I've been very interested in APIs, specifically in how to create them. For the purpose of this question, let's say that I have created an ASP.NET MVC site that has some data on it; I want to create an API for this site. I have multiple questions about this: What type of API should I create? I know that REST and oData APIs are very popular. What are the pros and cons of each, and how do I implement them? From what I understand so far, REST APIs with ASP.NET MVC would just be actions that return JSON instead of Views, and oData APIs are documented here. How do I handle writing? Reading from both API types is quite simple. However, writing is more complex. With the REST approach, I understand that I can use HTTP POST, but how do I implement authentication? Also, with oData, how does writing work in the first place? How do I implement basic rate-limiting and caching? From my past experience with APIs, these are very important things, so that the API server isn't overloaded. What's the best way to set these two things up? Can I get some sample code? Any code that relates to C# and ASP.NET MVC would be appreciated. Thanks in advance! While this is a broad question, I think it's not too broad... :) There are some similar questions to this one that are about APIs, but I haven't found any that directly address the questions I outlined here.

  • ASP.NET output caching - dynamically update dependencies

    - by ColinE
    Hi All, I have an ASP.NET application which requires output caching. I need to invalidate the cached items when the data returned from a web service changes, so a simple duration is not good enough. I have been doing a bit of reading about cache dependencies and think I have the right idea. It looks like I will need to create a cache dependency to my web service. To associate the page output with this dependency I think I should use the following method: Response.AddCacheItemDependency(cacheKey); The thing I am struggling with is what I should add to the cache? The dependency my page has is to a single value returned by the web service. My current thinking is that I should create a Custom Cache Dependency via subclassing CacheDependency, and store the current value in the cache. I can then use Response.AddCacheItemDependency to form the dependency. I can then periodically check the value and for a NotifyDependencyChange in order to invalidate my cached HTTP response. The problem is, I need to ensure that the cache is flushed immediately, so a periodic check is not good enough. How can I ensure that my dependant object in the cache which represents the value returned by the web service is re-evaluated before the HTTP response is fetched from the cache? Regards, Colin E.

  • Django caching seems to be causing problems

    - by Issy
    Hey guys, i have just implemented the Django Cache Local Memory back end in some my code, however it seems to be causing a problem. I get the following error when trying to view the site (With Debug On): Traceback (most recent call last): File "/usr/lib/python2.6/dist-packages/django/core/servers/basehttp.py", line 279, in run self.result = application(self.environ, self.start_response) File "/usr/lib/python2.6/dist-packages/django/core/servers/basehttp.py", line 651, in __call__ return self.application(environ, start_response) File "/usr/lib/python2.6/dist-packages/django/core/handlers/wsgi.py", line 245, in __call__ response = middleware_method(request, response) File "/usr/lib/python2.6/dist-packages/django/middleware/cache.py", line 91, in process_response patch_response_headers(response, timeout) File "/usr/lib/python2.6/dist-packages/django/utils/cache.py", line 112, in patch_response_headers response['Expires'] = http_date(time.time() + cache_timeout) TypeError: unsupported operand type(s) for +: 'float' and 'str' I have checked my code, for caching everything seems to be ok. For example, i have the following in my middleware. MIDDLEWARE_CLASSES = ( 'django.contrib.sessions.middleware.SessionMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.middleware.cache.UpdateCacheMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.cache.FetchFromCacheMiddleware', 'django.contrib.flatpages.middleware.FlatpageFallbackMiddleware', ) My settings for Cache: CACHE_BACKEND = 'locmem://' CACHE_MIDDLEWARE_SECONDS = '3600' CACHE_MIDDLEWARE_KEY_PREFIX = 'za' CACHE_MIDDLEWARE_ANONYMOUS_ONLY = True And some of my code (template tag): def get_featured_images(): """ provides featured images """ cache_key = 'featured_images' images = cache.get(cache_key) if images is None: images = FeaturedImage.objects.all().filter(enabled=True)[:5] cache.set(cache_key, images) return {'images': images} Any idea what could be the problem, from the error message below it looks like there's an issue in django's cache.py?

  • Classic ASP application-wide initializations and object caching

    - by slack3r
    In classic ASP (which I am forced to use), I have a few factory functions, that is, functions that return classes. I use JScript. In one include file I use these factory functions to create some classes that are used throughout the application. This include file is included with the #include directive in all pages. These factory functions do some "heavy lifting" and I don't want them to be executed on every page load. So, to make this clear I have something like this: // factory.inc function make_class(arg1, arg2) { function klass() { //... } // ... Some heavy stuff return klass; } // init.inc, included everywhere <!-- #include FILE="factory.inc" --> // ... MyClass1 = make_class(myarg01, myarg02); MyClass2 = make_class(myarg11, myarg12); //... How can I achieve the same effect without calling make_class on every page load? I know that I can't cache the classes in the Application object I can't use the Application_OnStart hook in Global.asa I could probably create a scripting component, but I really don't want to do that So, is there something else I can do? Maybe some way to achieve caching of these classes, which are really objects in JScript. PS: [further clarification] In the above code "heavy stuff" is not so heavy, but I just want to know if there's a way to avoid it being executed all the time. It reads database meta information, builds a table of the primary keys in the database and another table that resolves strings to classes, etc.

  • caching previous return values of procedures in scheme

    - by Brock
    In Chapter 16 of "The Seasoned Schemer", the authors define a recursive procedure "depth", which returns 'pizza nested in n lists, e.g (depth 3) is (((pizza))). They then improve it as "depthM", which caches its return values using set! in the lists Ns and Rs, which together form a lookup-table, so you don't have to recurse all the way down if you reach a return value you've seen before. E.g. If I've already computed (depthM 8), when I later compute (depthM 9), I just lookup the return value of (depthM 8) and cons it onto null, instead of recursing all the way down to (depthM 0). But then they move the Ns and Rs inside the procedure, and initialize them to null with "let". Why doesn't this completely defeat the point of caching the return values? From a bit of experimentation, it appears that the Ns and Rs are being reinitialized on every call to "depthM". Am I misunderstanding their point? I guess my question is really this: Is there a way in Scheme to have lexically-scoped variables preserve their values in between calls to a procedure, like you can do in Perl 5.10 with "state" variables?

  • Is MySQL caching occurring, how to fix it?

    - by rlb.usa
    I think that MySQL or ASP.NET is caching my queries. I edited my MySQL sproc to remove some parameters but it keeps saying that those parameters are missing. Here is what happens: ASP.NET app calls a MySQL stored procedure. Everything works perfect. I delete some parameters from the sproc and ASP.NET parameter list accordingly. All parameters exactly match in case and order from the new ASP.NET and MySQL sproc code Upon execution, it fails, saying : System.ArgumentException: Parameter 'deleted_parameter_foo_bar' not found in the collection. at MySql.Data.MySqlClient.MySqlParameterCollection ... I delete the sproc from the database, restart my browser, and reexecute the ASP.NET page. It says the same error, that the parameter is missing - but the sproc itself doesn't exist anymore. ( I know 100% that I am editing/deleting from the right database. ) How do I fix this or make it work again; I want it to use my new sproc instead of the old one ? _o

  • jQuery variable and object caching

    - by niksy
    This is something that has been bugging me some time and every time I found myself using different solution for this. So, I have link in my document which on click creates new element with some ID. <a href="#" id="test-link">Link</a> For the purpose of easier reusing, I would like to store that new elements ID in a variable which is jQuery object var test = $('#test'); On click I append that new element on body, new element is DIV $('body').append('<div id="test"/>'); And here goes the main "problem" - if I test this new elements length with test.length it first returns 0 and later 1. But, when I test it with $('#test').length it returns 1 from the start. I suppose it is some caching mechanism and I was wondering is there better, all-around solution which will allow to store elements in variables in the start for later repurpose and in the same time work with dynamically created elements. Live, delegate, something else? What I do sometimes is create string and add it to jQuery object but I think this is just avoiding the real issue. Also, using .find() inside another jQuery object. Thanks in advance.

  • Generating cache file for Twitter rss feed

    - by Kerri
    I'm working on a site with a simple php-generated twitter box with user timeline tweets pulled from the user_timeline rss feed, and cached to a local file to cut down on loads, and as backup for when twitter goes down. I based the caching on this: http://snipplr.com/view/8156/twitter-cache/. It all seemed to be working well yesterday, but today I discovered the cache file was blank. Deleting it then loading again generated a fresh file. The code I'm using is below. I've edited it to try to get it to work with what I was already using to display the feed and probably messed something crucial up. The changes I made are the following (and I strongly believe that any of these could be the cause): - Revised the time difference code (the linked example seemed to use a custom function that wasn't included in the code) Removed the "serialize" function from the "fwrites". This is purely because I couldn't figure out how to unserialize once I loaded it in the display code. I truthfully don't understand the role that serialize plays or how it works, so I'm sure I should have kept it in. If that's the case I just need to understand where/how to deserialize in the second part of the code so that it can be parsed. Removed the $rss variable in favor of just loading up the cache file in my original tweet display code. So, here are the relevant parts of the code I used: <?php $feedURL = "http://twitter.com/statuses/user_timeline/#######.rss"; // START CACHING $cache_file = dirname(__FILE__).'/cache/twitter_cache.rss'; // Start with the cache if(file_exists($cache_file)){ $mtime = (strtotime("now") - filemtime($cache_file)); if($mtime > 600) { $cache_rss = file_get_contents('http://twitter.com/statuses/user_timeline/75168146.rss'); $cache_static = fopen($cache_file, 'wb'); fwrite($cache_static, $cache_rss); fclose($cache_static); } echo "<!-- twitter cache generated ".date('Y-m-d h:i:s', filemtime($cache_file))." -->"; } else { $cache_rss = file_get_contents('http://twitter.com/statuses/user_timeline/#######.rss'); $cache_static = fopen($cache_file, 'wb'); fwrite($cache_static, $cache_rss); fclose($cache_static); } //END CACHING //START DISPLAY $doc = new DOMDocument(); $doc->load($cache_file); $arrFeeds = array(); foreach ($doc->getElementsByTagName('item') as $node) { $itemRSS = array ( 'title' => $node->getElementsByTagName('title')->item(0)->nodeValue, 'date' => $node->getElementsByTagName('pubDate')->item(0)->nodeValue ); array_push($arrFeeds, $itemRSS); } // the rest of the formatting and display code.... } ?> ETA 6/17 Nobody can help…? I'm thinking it has something to do with writing a blank cache file over a good one when twitter is down, because otherwise I imagine that this should be happening every ten minutes when the cache file is overwritten again, but it doesn't happen that frequently. I made the following change to the part where it checks how old the file is to overwrite it: $cache_rss = file_get_contents('http://twitter.com/statuses/user_timeline/75168146.rss'); if($mtime > 600 && $cache_rss != ''){ $cache_static = fopen($cache_file, 'wb'); fwrite($cache_static, $cache_rss); fclose($cache_static); } …so now, it will only write the file if it's over ten minutes old and there's actual content retrieved from the rss page. Do you think this will work?

  • Enabling browser caching via java

    - by Franz See
    Good day, I am using CacheFilter to filter a certain path to my server (which outputs an image stream to the response stream). And I've configured it in my web.xml as follows: <filter> <filter-name>imagesCache</filter-name> <filter-class>com.samaxes.cachefilter.presentation.CacheFilter</filter-class> <init-param> <param-name>privacy</param-name> <param-value>public</param-value> </init-param> <init-param> <param-name>expirationTime</param-name> <param-value>2592000</param-value> </init-param> </filter> ... <filter-mapping> <filter-name>imagesCache</filter-name> <url-pattern>/my/path/*</url-pattern> </filter-mapping> Using my firefox, if I access my url via the address bar, it hits the server the first time but uses the cache during succeeding calls. However, if the url is inside my page ( i.e. <img src="..."/> ), it seems to hit the server all the time. [EDIT] After a few more testing, accessing my image via the address bar does not work all the time. But caching does seem to work more often with it than . As to whether it really, I am not sure. Additional Info: my path is something like /my/path?then=some&query=strings. Notice that it doesn't have an extension (i.e. gif, png, jpeg ) but it's mimetype is set properly ( image/gif, image/png, image/jpeg ). I am not sure if the lack of extension or the presence of the query strings have any impact. (Also, another note. though my url have query strings, I am using the same uri + query string over and over again with my tests). Any ideas why? Thanks

  • Nested partial output caching in asp.net mvc 3

    - by Anwar Chandra
    Hi All, I am using Razor view engine in ASP.Net MVC 3 RC 2 this is part of my view city.cshtml (drastically simplified for the sake of simple example) <!-- in city.cshtml --> <div class="list"> @foreach(var product in SQL.GetProducts(Model.City) ) { <div class="product"> <div>@product.Name</div> <div class="category"> @foreach(var category in SQL.GetCategories(product.ID) ) { <a href="@category.Url">@category.Name</a> » } </div> </div> } </div> I want to cache this part of my output using OutputCache attribute. so I created an action ProductList with OutputCache attribute enabled <!-- in city.cshtml --> <div class="list"> @Html.Action("ProductList", new { City = Model.City }) </div> and I created the view in ProductList.cshtml as below <!-- in ProductList.cshtml --> @foreach(var product in Model.Products ) { <div class="product"> <div>@product.Name</div> <div class="category"> @foreach(var category in SQL.GetCategories(product.ID) ) { <a href="@category.Url">@category.Name</a> » } </div> </div> } but I still need to cache the category path output on each product. so I created an action CategoryPath with OutputCache attribute enabled <!-- in ProductList.cshtml --> @foreach(var product in Model.Products ){ <div class="product"> <div>@product.Name</div> <div class="category"> @Html.Action("CategoryPath", new { ProductID = product.ID }) </div> </div> } but apparently this is not allowed. I got this error.. OutputCacheAttribute is not allowed on child actions which are children of an already cached child action. I believe they have a good reason why they need to disallow this. but I really want this kind of nested Output Caching Please, any idea for a workaround?

  • Instance caching in Objective C

    - by zoul
    Hello! I want to cache the instances of a certain class. The class keeps a dictionary of all its instances and when somebody requests a new instance, the class tries to satisfy the request from the cache first. There is a small problem with memory management though: The dictionary cache retains the inserted objects, so that they never get deallocated. I do want them to get deallocated, so that I had to overload the release method and when the retain count drops to one, I can remove the instance from cache and let it get deallocated. This works, but I am not comfortable mucking around the release method and find the solution overly complicated. I thought I could use some hashing class that does not retain the objects it stores. Is there such? The idea is that when the last user of a certain instance releases it, the instance would automatically disappear from the cache. NSHashTable seems to be what I am looking for, but the documentation talks about “supporting weak relationships in a garbage-collected environment.” Does it also work without garbage collection? Clarification: I cannot afford to keep the instances in memory unless somebody really needs them, that is why I want to purge the instance from the cache when the last “real” user releases it. Better solution: This was on the iPhone, I wanted to cache some textures and on the other hand I wanted to free them from memory as soon as the last real holder released them. The easier way to code this is through another class (let’s call it TextureManager). This class manages the texture instances and caches them, so that subsequent calls for texture with the same name are served from the cache. There is no need to purge the cache immediately as the last user releases the texture. We can simply keep the texture cached in memory and when the device gets short on memory, we receive the low memory warning and can purge the cache. This is a better solution, because the caching stuff does not pollute the Texture class, we do not have to mess with release and there is even a higher chance for cache hits. The TextureManager can be abstracted into a ResourceManager, so that it can cache other data, not only textures.

  • IE dynamic image caching issue?

    - by rdevitt
    I have an html page that is loading multiple iframes into which are embedded dynamic images created from a Tomcat server page (.jsp). This works as expected from Chrome and Firefox, but for some reason IE displays all of the images the same (as the first image). I've created an example: http://coupondiscounts.com/dev/jsImageTest.html jsImageTest.html -- This page simply loads 6 instances of the testImageFrame.html page in separate iframes one-at-a-time, using Javascript. testImageFrame.html -- This is the page loaded in all the iframes. It contains only a JavaScript block that writes out the current time and an img tag. The img is dynamically generated by a .jsp page on a different server. It should be a white box on a black background. In the box are the current time (from the Tomcat server using Java) and a randomly created double between 0 & 1. What happens (in IE): The page almost instantly loads four identical iframes. Depending on the speed of your machine, the JavaScript times may vary by a second or two. The images' times will all be the same as will be the random number. This holds true even for the last two iframes which are loaded 5 and 10 seconds after the others (using JavaScript setTimeout()). What should happen (as it does in Chrome and FF): The page loads the same 4 iframes, but the random numbers in the images will be different. The times in the images occasionally span a second as well. Anyone have a clue as to what's going on here? Is IE doing some strange caching? The image header has "no-cache," "no-store" and all that. I've tried it on IE6 and 7. You can use the "Next" button to create another iframe. In IE, the images are always the same. Notes: I don't really need iframes, just the images, but if I only use img tags, the problem appears in Chrome and FF as well. I also don't really need to load these iframes dynamically, I was just trying to abstract the issue further and allow a delayed load for the latter 2 images.

  • Request.IsAuthenticated problem with Cache in ASP.NET

    Hello guys or girls..! I'm new in ASP.NET and I have a problem...

  • Bypass all cacheing on jQuery.autocomplete(1.02)

    - by technicalbloke
    I am using jQuery.autocomplete(1.02) on my search box and I want exact string and substring matching. I don't care (yet!) about the database load, I'm happy for it to fire off a query every keystroke and bypass the caching entirely - I just don't want anything missed. To this end I have tried setting cacheLength=1, the minimum permitted, but the autocomplete function refuses to fire off a GET request for each key up. searchbox GET_request 'a' -> http://localhost/service_search_request?q=a 'ar' -> http://localhost/service_search_request?q=ar 'ars' -> http://localhost/service_search_request?q=ars Instead, it sends the first and the third and misses the second, giving me the wrong results for 'ar' :-/ I've cleared my cache and sessions but it looks like some sort of caching is still going on. AFAIK I have no proxying going on and I'm shift-refreshing each time. It looks likely then that this behavior is from jQuery.autocomplete itself. So my questions are... A) Does this seem likely? i.e. is it a feature, or maybe a bug? B) If so is there a clean way around it?... C) If not, what autocomplete would you use instead? Naturally D) No you're just using it incorrectly you douche! is always a possibility, and indeed the one I'd prefer having spent time going down this road - assuming it comes with a link to the docs I've failed to find / read!

  • Thread Local Memory, Using std::string's internal buffer for c-style Scratch Memory.

    - by Hassan Syed
    I am using Protocol Buffers and OpensSSL to generate, HMACs and then CBC encrypt the two fields to obfuscate the session cookies -- similar Kerberos tokens. Protocol Buffers' API communicates with std::strings and has a buffer caching mechanism; I exploit the caching mechanism, for successive calls in the the same thread, by placing it in thread local memory; additionally the OpenSSL HMAC and EVP CTX's are also placed in the same thread local memory structure ( see this question for some detail on why I use thread local memory and the massive amount of speedup it enables even with a single thread). The generation and deserialization, "my algorithms", of these cookie strings uses intermediary void *s and std::strings and since Protocol Buffers has an internal memory retention mechanism I want these characteristics for "my algorithms". So how do I implement a common scratch memory ? I don't know much about the rdbuf(streambuf - strinbuf ??) of the std::string object. I would presumeably need to grow it to the lowest common size ever encountered during the execution of "my algorithms". Thoughts ? My question I guess would be: " is the internal buffer of a string re-usable, and if so, how ?" Edit: See comments to Vlad's answer please.

  • How can I exclude pages created from a specific template from the CQ5 dispatcher cache?

    - by Shawn
    I have a specific Adobe CQ5 (5.5) content template that authors will use to create pages. I want to exclude any page that is created from this template from the dispatcher cache. As I understand it currently, the only way I know to prevent caching is to configure dispatcher.any to not cache a particular URL. But in this case, the URL isn't known until a web author uses the template to create a page. I don't want to have to go back and modify dispatcher.any every time a page is created--or at least I want to automate this if there is no other way. I am using IIS for the dispatcher. The reason I don't want to cache the pages is because the underlying JSPs that render the content for these pages produce dynamic content, and the pages don't use querystrings and won't carry authentication headers. The pages will be created in unpredictable directories, so I don't know the URL pattern ahead of time. How can I configure things so that any page that is created from a certain template will be automatically excluded from the dispatcher cache? It seems like CQ ought to have some mechanism to respect HTTP response/caching headers. If the HTTP response headers specify that the response shouldn't be cached, it seems like the dispatcher shouldn't cache it--regardless of what dispatcher.any says. This is the CQ5 documentation I have been referencing.

  • Ruby On Rails with HTML5 offline apps - Firefox does not cache the application.manifest but Safari does

    - by hoitomt
    I'm working off of this Railscast tutorial: episode 247 I’m up to this point in the tutorial: added the rack-offline gem, added the application.manifest route, and added a reference to the manifest in the html tag. Right before it starts talking about problems with caching. Safari works as intended – When the server is running the page is served. From the server logs I can see that Safari is making a single request to the server every time for the items page. When I turn off the server the page displays as well, even after shutting down the browser and restarting. It appears to be pulling from the application.manifest (cache manifest). Firefox does not work as intended – When accessing the page for the first time, Firefox lets me know that the web page wants to store something locally, I allow. After clicking on allow, Firefox makes 5 requests to the server for the page (from the server log). The hash is different in every request. Is it is possible that the changing hash is triggering Firefox to keep trying to get the new manifest until it reaches some maximum (5 attempts)? Then, after the server is stopped, Firefox will not show the page at all. It looks like it isn’t caching the application.manifest. Firefox also gives you a way to see what sites are storing stuff locally by going to Tools/Options/Advanced/Network (Firefox/Preferences/Advanced/Network on Apple). I see localhost there but the size is 0 bytes. So for some reason, Firefox is not downloading my application.manifest along with the files

  • When to address managed heap fragmentation

    - by emddudley
    I was reading a blog entry by Josh Smith where he used a cache mechanism in order to "reduce managed heap fragmentation". His caching reduces the number of short-lived objects being created at the cost of slightly slower execution speed. How much of a problem is managed heap fragmentation in a managed language like C#? How can you diagnose if it's an issue? In what situations would you typically need to address it?

  • How do I cache WCF REST web service in IIS7?

    - by foosnazzy
    When I turn on output caching for my service it doesn't appear to be cache-worthy in IIS. It really should be since I'm returning the same JSON content over and over. The varyByQueryString option seems like it would do the trick, but since my resources are URI based, there really isn't a query string, just a path to a resource. Has anyone successfully gotten IIS to output cache a WCF REST service?

I would like to know if there is a way to initiate the page caching on the server side and serve the cached page upon the very first request, rather than have it triggered by the user one first time. Any ideas/suggestions will be very much welcome. Best regards, TT
