PHP Version Of .NET's SqlCacheDependency?

Nov 30, 2010

I find the SqlCacheDependency very useful when writing C# ASP.NET applications, and would love to use something similar in my PHP applications. Can anyone suggest something?

SqlCacheDependency caches the page page output forever, until the specified table(s) are modified in the database.

Here's the basic jist of what happens in ASP.NET:

SqlCacheDependency SqlDep = null;
// Check the Cache for the SqlSource key.
// If it isn't there, create it with a dependency [code]...

So does anyone know of any MySql table dependency technique? - much cleaner than time-based caching.

Firefox Version Wrong With Request.Browser.Version?

Sep 26, 2010

I'm try to get my site to detect what browser someone is using to ensure they're using one that is compliant with our site. Everything works, except Firefox seems to post the wrong version in the Request.Browser variables.I'm on Firefox 3.6.10, but Request.Browser shows Mozilla 1.9.2.10. It's correct in the HTTP_USER_AGENT string:

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.10) Gecko/20100914 YFF35 Firefox/3.6.10 ( .NET CLR 3.5.30729)

Is there a way to detect it better without having to parse through the HTTP_USER_AGENT string?

C# - FormsAuthenticationTicket.Version Returns Invalid Version Number

Mar 8, 2011

Is there any limit on the size/numbers in the version number of the FormsAuthenticationTicket.

I tried to create an ASP.NET cookie using forms authentication, with a large version number(ex: 1234567 need this number for identification purposes). But when I decrypt the cookie I get 135 as the version number.

Initially the old forms authentication cookie was removed, in order to add new information.

Response.Cookies.Remove(FormsAuthentication.FormsCookieName);

Following is the code I used to create the FormsAuthentication cookie.

FormsAuthenticationTicket newAuthTicket = new FormsAuthenticationTicket(1234567, un, DateTime.Now, DateTime.Now.AddHours(5F), false, user_data);
HttpCookie newauthCookie = new HttpCookie(FormsAuthentication.FormsCookieName, FormsAuthentication.Encrypt(newAuthTicket));
Response.Cookies.Add(newauthCookie);

After retrieving the cookie, the version number I got was 135. This number varies with different version numbers.

string cookieName = FormsAuthentication.FormsCookieName;
HttpCookie authCookie = Context.Request.Cookies[cookieName];

if (authCookie == null)
{
return;
}
FormsAuthenticationTicket authTkt = null;
authTkt = FormsAuthentication.Decrypt(authCookie.Value);
if (authTkt == null)
{
return;
}
int versionID = authTkt.Version;

Can someone let me know if it's a bad idea to use such big version numbers, or am I missing something in this.

DataSource Controls :: Version 661. This Server Supports Version 655

May 22, 2010

I have Visual Studio 2008 installed on this workstation with SQL 2000, 2005 Express, 2008 Express and I think 2008 R2 (not sure if that is a version itselve or not)

I will call that workstation HOME

I created some tables in SQLEXPRESS through VS2008.

I worked on this project on another workstation that I just installed VS2008 annd SQLEXPRESS 2008 and I know that was R2

Installed Visual Studio 2010 trial edition between the thiem I made the tables on HOME and tonight for the first time since that install

I am now getting the "cannot be opened becuase it is version Version 661. This Server supports version 655..."

What to do now?

I can opened SQLExpress 2008 management studio and it is running.

So is my SQL 2000. The problem seems to be that after the VS2010 install neither VS2008 or VS2010 can connect to the SQLExpress 2008

What do I do now?

I can't remove sql 2000 because it is tied to several 3+ gig databases that will not work in Express.

SqlDependency Vs SqlCacheDependency

Oct 11, 2010

What are the key differences between these and when should they be used? My initial understanding was that SqlCacheDependency used polling but I've read it doesn't have too for ASP.NET 2.0. I want to know which is most appropriate for caching of linq queries under ASP.NET web server. This will be ASP.NET 3.5.

SqlCacheDependency Not Deleting What Is In Cache

Feb 2, 2011

I am using sqlCacheDependency, and usually upon any changes in the database cache items get deleted automatically. In my case everything works allright, but I had to buy a new laptop and I moved the same exact database and the same exact webapplication to the new laptop. Unfortunately, on my new machine the cache items remain in cache upon data updates on the database.

I have enabled servicebroker on the database, and started it in the application_start event in my webapplication. I also ran the following:

GRANT SUBSCRIBE QUERY NOTIFICATIONS
TO "Naji-pcNaji"

The differance I see on my laptop from my other machine is that the database is named (local). Naji-pc is the name of my machine.

State Management :: Sqlcachedependency Is Not Working

Jul 21, 2010

My Asp.Net app caches some lookup DataTables to avoid hitting DB for seldomly changed data. When the data does change, however, I would like to use the sqlCacheDependency to get SQL Server to send a notification to my application, which should then reload the table into the cache.

In my application, the callback is not being executed, and the cache is not updated when data is changed in SQL Server.

I am using SQL 2005. This is my code:

.net - Using SqlCacheDependency To Get Real Time Updates?

Jan 9, 2010

I would like to display real time updates on a web page (based on a status field in a database table that is altered by an external process). Based on my research, there are several ways of doing this.

Long Polling (Comet) - This seems to be complex to implement Regular Polling - I can have an AJAX method trigger a database hit every 5seconds to get the current status. But I fear this will have performance issues.

Then I read about using SqlCacheDependency - basically the cache gets invalidated based on a field in the table. I am assuming I can use the event trigerred when the cache is invalidated to show the new update to the user?

DataSource Controls :: SqlCacheDependency For Same Table Name In Different Schemas?

That works, but I can't register same table name for different schemas, for example dbo.MyTable and MySchema.MyTable.In column tableName in table AspNet_SqlCacheTablesForChangeNotification there are only table names without schemas.

Is it possible to register same table names and different schemas?

State Management :: Queries Supported By SqlCacheDependency?

Apr 20, 2010

In our project we have planned to put cache dependency on the queries, such that whenever the query result changes the cache gets invalidated. The problem is most of our queries use Distinct, top and group by. As I have learnt that SqlCacheDependency does not support queries with Distinct and Top, So, how should we proceed to implement the query dependency when the queries are complex.

Web Forms :: Create A SqlCacheDependency With CommandNotification In Code

Jul 19, 2010

I have an ASP.NET 3.5 web page that tries to retrieve a DataSet from a cache object. If not available, it will be retrieved from the database (SQL Server 2005) and I will insert the newly retrieved DataSet into the Cache object. The problem is that I want to insert the DataSet with a SqlCacheDependency so that as soon as the database table changes, my ASP.NET application will be notified. Something that is accomplished in @PageOutput using SqlDependency="CommandNotification". SqlCacheDependency constructor has two overloads, neither of which seems to be able to resolve my problem. I have no idea where I can set that magical CommandNotification!

C# - Cache Is Not Invalidated After Table Update Using The SqlCacheDependency?

Apr 28, 2010

I have been trying to get SqlCacheDependency working. I think I have everything set up correctly, but when I update the table, the item in the Cache isn't invalidated.

I enabled the Service Broker for the Sandbox database.I have placed the following code in the Global.asax file. I also restart IIS to make sure it is called.

void Application_Start(object sender, EventArgs e) {
SqlDependency.Start(ConfigurationManager.ConnectionStrings["SandboxConnectionString"].ConnectionString);
}

I have placed this entry in the web.config file:

<system.web>
<caching>
<sqlCacheDependency enabled="true" pollTime="10000">[code]....

I call this code to put the item into the cache:

protected void CacheDataSetButton_Click(object sender, EventArgs e) {
using (SqlConnection sqlConnection = new SqlConnection(ConfigurationManager.ConnectionStrings["SandboxConnectionString"].ConnectionString))[code].....

Then I bind the GridView with this code:

protected void BindGridViewButton_Click(object sender, EventArgs e) {
if (Cache["Pets"] != null) {
GridView1.DataSource = Cache["Pets"] as DataSet;
GridView1.DataBind();
}
}

Between attempts to DataBind the GridView, I change the table's values expecting it to invalidate the Cache["Pets"] item, but it seems to stay in the Cache indefinitely.

DataSource Controls :: Setup SqlCacheDependency Without Using Web.config

Jan 7, 2010

I have setup and SqlCacheDependency for my site and all is working well, but there is one requirement in my task that I dont' seem to be able to find the workaround for. Currently, my code relies on the following web.config settings to allow the SqlCacheDependency to know where to connect to. it is like this:

<connectionStrings>
<add name="connstring1" connectionString="......" />
</connectionStrings>
<caching>
<sqlCacheDependency enabled="true" pollTime="500">
<databases>
<add name="db1" connectionStringName="connstring1" pollTime="500" />
</databases>
</sqlCacheDependency>
</caching>

The problem is that we can't allow in our application the connectionstring to be on the web.config. I am asked to programmatically do all of that. I don't know how and I don't know if that is even possible, is it?

AJAX :: The Requested Script Resource 'Common.Common.js' Requires Version 'ControlToolkit, Version=4?

Aug 11, 2010

I have a solution I'm working on in VS2010 Professional, using ASP.NET 4.0 with the AJAX Toolkit.This has been working fine, but when I started it up today, I got the runtime exception shown above. This exception occurs on any page with a control from the toolkit.Sometimes when I load a page, I get an exception "Could not load file or assembly 'System.Windows, Version=2.0.5.0, Culture=neutral, ublicKeyToken=7cec85d7bea7798e' or one of its dependencies. The system cannot find the file specified." If I then reload the page (without making any changes), I then get the exception shown in the subject line.I tried dragging an AJAX Toolkit control from the toolbox onto a page, and then deleting it, and that worked - once. The next time I tried the page (or any other), I got the exception again. Dragging a control out didn't help this time.
