Server Side Caching Doesn't Work With HttpHandler?
Mar 15, 2010
If we use an aspx page with a Caching Profile, the server caches images that are loaded with the aspx page. So if ten clients load the same image through the aspx page (same url), for one client the image is gotten out of the db, for the nine others it is cached.When we use a HttpHandler, this doesn't happen. The image is always fetched from the database. We have tried all different settings without any success. (we have checked this link and have not been able to cache on server side).
I have put the following method in my master page. It works when I call it on a full post back, but when I call it from a updatePanel's asyncPostBack no alert is shown.
I am trying to use output caching on my .net pages but it is not working when I use Route handlers to redirect request to actual page, but it works when I call the page directly.
also one more weird thing is that when I am debugging and using .net instance of IIS http://localhost:64293/test it is working, but when I deploy it and try to call the page it is not caching i.e. http://www.mydomain/test(but it works if I call the page directly)
My asp.net app is heavily using user controls and is high load; my concern is that loading user controls for every request (Page.LoadControl(controlPath)) is sub-optimal at best. I was thinking of caching an instance of loaded user control in HttpRuntime, but I don't know how's it going to behave when multiple connections (threads) will try to fetch it from the cache and modify properties - I guess trouble is waiting there. Any good way to optimize user control loading?
Again, I am talking about caching user control, not it's html output (which it makes no sense caching as it's [html output] going to be different every time you use it)
Just I started learning MVC pattern, of course i am learning it from Microsoft's website.Just i want to gather quiz information from the experts. My understanding is (correct me then and there)
1 ) MVC does not support server side events, but supports client side events. If it supports client side events, I need html page with jQuery/Javascript (view), but most of the example I absorbed is to display the information(model) in view, I did not see any client side event handling happens in view.
2) Except ViewState and controlState, MVC supports Sessions, Application State management, Cache management.
3) When request goes to MVC engine, the routing module routes the request that is picked up by the controller. The controller in executes the appropriate action and returns the appropriate view.
I have a webdayview control (Infragistics proprietary ASP.net control) on my page. On the aspx source I've inserted some javascript (webdayview_click - clientside click event) that calls a webmethod in the codebehind. This seems to work fine, but when I insert this webdayview control into a user control and move the corresponding javascript into the aspx of the user control, it doesn't work. I can't even insert a breakpoint into the javascript function to debug it. Is there a way to make it work? I want to enable the click event of the webdayview control so that when I click on it, the javascript function calls the webmethod. Here's my code (remember it is inside a user control):
[code]...
I posted this question on the Infragistics forum but didn't get any replies. Hopefully I'll get some here. :)
Does anyone know of any requirements to get the Ajax Control Toolkit (Calendar Extension in particular) working in this OS? I have it working on my local macjine (VS 2010 Development Server) but it doesn't work when published to my Virtual Server running Windows Server 2008 R2. No errors are reported, just nothing happens when I give focus to the Calendar textbox (no Calendar appears).Anyone know of any configutrations that need to be made in Windows Server 2008 R2?Is there a 32-bit/64-bit issue with the Toolkit?
I'm implementing Outputcache in my application and it works fine, but the first time always take a lot to load and the next following request will be faster...
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.
I have a big problem in using SqlCacheDependency and Sqlserver notification service.I just want to add a dataset to cache with a SqlCacheDependency and get expire notification from sql server , Here is the simple code that doesn't work
(.net 4 , sqlserver 2008)
private DataSet GetData()
{[code]....
I have enabled my database service broker with : [alter database dbName set ENABLE_BROKER] I have created a master key for my databese with : [CREATE MASTER KEY ENCRYPTION BY PASSWORD = '1']
There is no error in sql server log file but when I change my skin table data , my cached dataset still remains in cache , it seems that there is no notification from sql server about changing the result of my Sqlcmd (that the SqlCacheDependency is created on it)
I have the below stored procedure witch has an error I cann't figure out.
What I want: Gets rankOrder. If rankOrder doesn't have a value (= null) the @num should be insertet as 1 as value. If there is a row and a rankOrder is should set the @num to insert the value + 1. The last one works perfect. But when the row I select is emty = null value the value is set to null in the insert command.
I created a web application which uses AJAX. When I debug the application on my local C drive it works fine. When I move it over to my shared server F drive and debug it, I get permission errors for every time I used AJAX in the web application. The errors look like this:
Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. F:JoshAJAXCCRSchedulingTESTShiftScheduleVsWorked.aspx
I have done almost everything including set my security level to full trust (which is what most people say is all i have to do). I do not know what else to try. Any other ideas? Could it be because I am on the .net framework 1.1 configuration? Do I need to add something to it?
I have a column in my .mdf file with the 'uniqueidentifier' datatype. I would like to have it set by SQL Server Express automatically. There are articles on the web that recommend using one of the following commands as the default value:NEWID()NEWSEQUENTIALID()I put this in VS 2010 column properties of my table, in Default Value or Binding. The first command works fine but the second turns out showing an error message 'error validating the default for column xxxx'Any advice on this? I'm I missing much using the first command?
I booked new server and transfer old website to there I using in this site the ajax just updatepanel it's was works on old server without need to copy ajax dll to Bin folder after I transferred the site it's doesn't work and no any page error i tried copy ajax dll to bin folder but same problem.
Note:I installed on server .Net 4.0 and the site works on 3.5 also ajax was v3.5 i think the .Net 4 enough to run all.
<asp:CustomValidator ID="valSex" runat="server" ErrorMessage="1.2 <b>Sex</b> not specified"[code]...
When the page is submitted and Sex is not specified, focus is set but the 2 radio buttons are not quite in view, vertical scrolling is required to bring them into view. Shouldn't the Focus() method have brought the focus control into view?
<asp:CompareValidator ID="cpvBirthDate" Type="Date" ControlToValidate="txtBirthDate" Operator="DataTypeCheck" runat="server" ErrorMessage="Please enter a valid date in this format mm-dd-yy"> <img src="Images/ExclamationMark.gif" alt="Please enter a valid date in this format mm-dd-yy" /> </asp:CompareValidator>
It works on the clientside fine, but if a user has javascript disabled then it accepts 071873 which is not a date. Do I need to write a specific serverside function for this validator to work?
I have an MVC2 application, and HttpHandler Library. The library, to simplify, serves an image. The problem is that if I invoke this handler from the root page ( http://whatever/ ), everything works fine. If, however, I change the Global.asax, so the same page now has the address of http://whatever/controller/action - it doesn't work (ALT text comes out instead of image).I didn't write the handler library, but I have the code; so I put a breakpoint in ProcessRequest function of IHttpHandler implementation. For good situation the breakpoint gets triggered, but for bad case it isn't. So, I assume that the handler isn't invoked for non-root pages.
I'm trying to create a HTTP handler to handle all requests to a folder but I only want it to fire if the files requested don't exist (EG: Request comes in for file X, if X exists I'd like to serve the file, otherwise the handler should deal with it).The files will only be static content, not scripts themselves, which I assume makes it a bit easier but I can't seem to find anything that will do the trick... Anyone have any ideas? I assume it can be done since the IIS7 rewrite module can manage it, but I can't see how...Edit Just to clarify... the handler is the typical case and it is not an error-handling routine but actually delivering appropriate content. I just want the ability to add new files to the folder either as separate things or as overloads to what the handler would deliver.
i am using mod_aspdotnet.so module to hosting my ASP.NET application. all was ok until i use ajax control tool kit in my aplication. I am using ajaxToolkit:CascadingDropDown to conect 2 dropdownlist in cascade. In IIS every thing works fine, but in apache there are some problems. When load the page, i got the next javascript error: 'Sys' undefined. the object signed are :
and on change of this dropdownlist i check if the its text equal to a string i show the 2 tr as below
function ValidateCity() { if ($('#<%= citiesDropDownList.ClientID %> :selected').text() == identity_CityOther) { $('#<%= otherCityTR.ClientID %>').show(); $('#<%= areasTR.ClientID %>').show(); } var city = $('#<%= citiesDropDownList.ClientID %>').val(); return IsValid((city.length != 0), '#<%= cityDiv.ClientID %>', identity_CityRequired); }
.show() isn't work at all and i don't the reason .. can any lead me to get the problem?
FYI : I tried $('#<%= otherCityTR.ClientID %>').show('slow'); and also $('#<%= otherCityTR.ClientID %>').css('visibility', 'visible'); but it doesn't work also.
