As part of the deployment, we need to have a maintenance page displayed for our web site. The issue we are experiencing is that when the maintenance page is active and ISA rule is configured to redirect to the maintenance page. We see the following behavior:
The user is not displayed the maintenance page, but is displayed a splash page with the English and French buttons. Click on any button displayed a 404 error regarding the URL / File not found. After clearing the local cache and reloading the browser, the maintenance page is displayed successfully.
The same behavior is noticed one we have disabled the ISA rule for the maintenance page and re-enabled the ISA rule for the the Website. The user is presented with the 404 error and once the cache is deleted, the user can see the Website.The issue is a cause by browser retrieving the website pages from the cache and not directly from the webserver.
I have an external javascript file which I include to my page on the code behind (as seen below).
My problem is, when I my page makes a postback (not partial one), I check the loaded scripts by using FireBug, and I cannot see the javascript file in the list after the post back. I asusmed once it is included to page on the first load, browser will be caching it so that I do not need to re-include it.
We have a wfc layer that wraps the business classes and database access and use a client that lives on the database layer. Amongst our group we are attempting to form standards. Some want to have the client call the web method and pass the page they are requesting and the page size. Pass that to the database and then page in SQL Server use RowNum.Some want to cache the full list of objects in http cache on the service tier and page in memory. They concern here is memory use on the server.
Which would be best for a medium number of users with potentially large number of records to manage (say 30K) Is it better to cache them all in memory and work from there or page at the database as the application scales?
I need to enable caching in my asp.net application, but I do not want to use the webserver's memory for holding cache objects. If I add the page directive for output caching will the page be stored in the asp.net cache object?
User X login as "user1" in web browser. Then user Y also login as "user1" also in another web browser. User Y got error message "Another user log in some account".
That is work as expected.
If X, close their web browser. Then try again to login in as "user1". X get also get "Another user log in some account".
So i trying debug then i found session is remove when web browser is close, but cache still remaining in web browser.
how to clear cache when user close their browser, (not tab).
I have a menu on my site that changes depending on whether the user is logged in or not. With browser caching, the menu "gets stuck" in either state and is confusing to users.They'll login, but the menu won't update because it's still cached in the unauthenticated state... and vice versa.How is this typically handled? Can we refresh the user's browser cache from our code? Or do I just not allow browser caching? (would rather use it, very nice bump in speed).UpdateHere's how I set client-side, browser caching in my asp.net mvc 2 app:
public class CacheFilterAttribute : ActionFilterAttribute { /// <summary> /// Gets or sets the cache duration in seconds. The default is 10 seconds.
i am using ScriptManager in my webpage. i am also using a lot of pagemethods in this page. When i look at the viewsource of the browser after the page has been rendered i find a lot of javascript which has been generated by the scriptmanager.
how can i browser cache all these scripts so that they are not loaded everytime the page is rendered.
Not sure if i'm posting in the right forum, if not, please move it...i have the following issue... I want to "disable" browser's back button. Seems it's not possible, but using cache.setcacheability and timing it, kinda disables the option of navigating back. I need this because in some pages of my webpage, i keep values in a Session variable so when a page loads, i need to check that variable, and, if navigating back, cant do that. I also "set cache to false" because if someone closes session, and i allow cache, someone else could handtype a url in that same pc and see the page without login (though if he/she tries to navigate through it will be kicked out because when loading a new page, i'll know that he/she is not logged) but i dont want to allow even that,
that's why cache is disabled. The problem is that loading over and over again my masterpage (header, footer, menu and stuff) is going to slow down the webpage, because every time there's a request, the page has to be sent again completely. So, is there something like a "mix" mode where i can allow cache just for a few things? If not, what's the best practice to achieve both things i'm trying: speed and security?
i am using Jcrop to give users the option to crop there images, i have hit a small caching problem.
if you open an image which is already on the server and crop it. my jcrop works and crops the image fine but when i reload the image the old version is displayed. i have this inside an update panel.
so is there a way of removing the browsers cache before i reload the image?
I have a form that has n dropdownlists, and the form has gotten so big that it now weights over 1.2MB...I was wondering, is it possible to load the datasource items once in the browser and have all related dropdownlist use that single datasource to conserve bandwidth?Something like, load datasource into div, and on page_load have all dropdownlist load from that div...
I am inserting and updating the image from html file upload to my gridview / insertion goes fine , but when i update the image by clicking on edit using onselectedindexchanged event of gridview, I fetch the image then change it with other image, with this simultaneously i rebind the gridview, in the beck-end everything goes fine it updates and replaces the image but in gridview it won't show after updated. I am using postbacktrigger on my submit button, but gridview won't refreshes, until and unless i click on address bar and press ENTER , or until i won't press CTRL+F5 to clear the browser cache.
I am using Html.RenderAction<CartController>(c => c.Show()); on my master Page to display the cart for all pages. The problem is when I add an item to the cart and then hit the browser back button. It shows the old cart (from Cache) until I hit the refresh button or navigate to another page.
I've tried this and it works perfectly but it disables the Cache globally for the whole page an for all pages in my site (since this Action method is used on the master page). I need to enable cache for several other partial views (action methods) for performance reasons.
I wouldn't like to use client side script with AJAX to refresh the cart (and login view) on page load - but that's the only solution I can think of right now.
Assume a simple aspx data entry page in which admin user can upload an image as well as some other data. They are stored in database and the next time admin visits that page to edit record, image data fetched and a preview generated and saved to disk (using GDI+) and the preview is shown in an image control.
This procedure works fine for the first time however if the image changes (a new one uploaded) the next time the page is surfed it shows previously uploaded image. I debugged the application and everything works correct. The new image data is in database and new preview is stored in Temp location however the page shows previous one. If I refresh the page it shows the new image preview. I should mention that preview is always saved to disk with one name (id of each record as the name).
I think that is because of IE and other browsers use client cache instead of loading images each time a page is surfed. I wonder if there is a way to force the client browser to refresh itself so the newly uploaded image is shown without user intervention.
My requirement is to get the file size in client side. there is no problem in FF but in IE you can't do that unless u r using an activeX object. So we thought of putting it in browser cache and reading the file size from there and when we post it to the server we will be taking it from the cache and send it to the server.
I've been developing an application using asp.net MVC, and I have some configurations that influences in process of render a view. For example, a user can choose (in an configuration of system) if a field should appear for a management of records in an area of the system. So, I have an class called AppConfiguration has some properties to represent this configurations.
I guess I need to cache an object of AppConfiguration, and make a ViewModel base class and inherits from my viewmodel, for example:
public class BaseViewModel { public AppConfiguration Config { get; set; } } public class DocumentViewModel : BaseViewModel { public Document Document { get; set; } }
and make typed views using "DocumentViewModel" to check the properties if this kind of document is able to render or not ? is it works ? Or is there any other better way to do something like this ?
I would like to set cache- control on a folder of images in a web application . In that way i can cache the images and the web pages will load a lot quicker . I can specify this in IIS by putting a ISAPI extension , but how can i do the same thing in asp.net application, ie create that setting in IIS when the application first starts up .
I'd like to pass data from one asp.net page to another. I've seen that using System.Web.Caching.Cache is a good way to accomplish this. I'm wondering if it's a good way to do it and also is there any cleanup or other things I need to keep in mind when you the Cache?
I have a Web Application where I have one and only one master page and with 100's of diffrent content pages
So to speed up my Web app How can i CACHE the mater oage but not the content page??
Master page loads each time whenever content page is requested..
This thing is possible,I have seen it on many diffrent websites where the Website's Master Page Remains Intact and only the content page changes (best example would be Facebook)
How can i have the same effect in my Web Application?
I get this error message when i try to open my site in the web browser... i'm not sure how to mix this problem.Configuration ErrorDescription:An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.Parser Error Message: Unrecognized attribute 'targetFramework'.
