I am having a problem passing JSON from PHP server and ASP.NET server.
I am getting Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 48 bytes)
I am looking for a way to compress the JSON.
I have this proxy code taken from this article and created as an HttpHandler
public void ProcessRequest(HttpContext context)
{
string url = context.Request["url"];
[code]...
I try to use the jquery + json to get all elements in form and build a JSON var to post in a ASP.NET MVC method.
[Code]....
It method get all fields in a form and build a JSON, but it dont put JSON inside JSON.
Example:
If i have the follow form:
<input name="person.name"><input name="person.age"><input name="person.address.street">
The serialized string build a JSON like this
{ "person.name": "??", "person.age": "??", "person.address.street": "??" }
I need a plugin or some function to generate like this:
{ "person": { "name" : "??", "age" : "??", "address":{ "street": "??" } } }
I have to let the user downloads a big text file.. By now I'm compressing the file with ".gz" (GZipStream)... And then the user can unzip in his machine.. But some users can't decompress the .gz extension.. And I wonder if there is any way to compress using zip..
View 2 RepliesJust spent a lot of time exorcising asp.net's large (but understandably useful) viewstate from an app, and i think it's worth sharing how it's done.
View 8 RepliesIn my web application I use an ashx file to write a file to the browser. I've noticed that there's no compression over the .ashx file, but only over my .aspx files.
Is it possible to compress .ashx? And if it is possible, how?
Currently I use global.asax to handle the compression:
<%@ Application Language="C#" %>
<%@ Import Namespace="System.IO" %>
<%@ Import Namespace="System.IO.Compression" %>
<script runat="server">
void Application_PreRequestHandlerExecute(object sender, EventArgs e)
{
HttpApplication app = sender as HttpApplication;.......
As you can see only files which inherit from 'Page' are compressed, and my ashx file is not of type Page. So I added a condition and now it works just fine:
if (!(app.Context.CurrentHandler is Page ||
app.Context.CurrentHandler.GetType().Name == "SyncSessionlessHandler" ||
app.Context.CurrentHandler is ViewMht // This is the type I had to add
) ||
app.Request["HTTP_X_MICROSOFTAJAX"] != null)
return;
I have ScriptResource.axd file which is use and whithout compression. also I have JavaScript files that are not compressed too.
this is making website loads reallu slow....20 seconds....:
What can I do to reduce this and compress everything?

I have a text file named gisQuery129.json that is created using Json.NET - [URL] There is an example on how to create a JSON file and I have done that successfully, but I want to read the file on a page load event and add the values to .NET textbox controls for input values in a query. The created file looks like the following:
{
"myData": {
"randomNumber": "129",
"Application": "MyMapApp",
"FeatureId": "ALL",
"Feature": "ALL",
"spatialQuery": "FEATURE_ID= '11111' AND REQ_SEQ_NUM= 1 AND RAND_PARAM= 129 OR FEATURE_ID= '22222' AND REQ_SEQ_NUM= 2 AND RAND_PARAM= 129"
}
}
I want to read the data in the above sample JSON data and then populate my textboxes something like this:
txtRandParam.text = "129"
txtApplication.text = "MyMapApp" and three more text boxes after that.

In the past, with pages with large viewstate I have overridden the PageStatePersister class so when the state is saved I compress it. On Load I decompress it. I have haven't really thought about it, but could IIS handle something like this better? The reason I did this was to keep my pages slimmer because I have a lot of custom controls on the page and the viewstate was huge. This is where I got my original code from:[URL]

View 1 RepliesI've been tasked with implementing a JSON feed on an asp.net website that will be consumed by 3rd party apps (such as IPhone, Android, etc) and I'd like to follow best practices.
An example of what I'd like to achieve would be something similar to: [URL]
I've chosen the JSON.net api as this seems to be highly recommended.
My Google-fu must be failing me as I can't find a single full example code for an Asp.net web application with JSON.net implemented on it, so I've no real concept of where to begin.
My question is fairly simple:
Should I create this sort of feed as an ASPX, or ASHX file? Or even a .NET Web Service? (Remember that the tools that will be using this feed are on external apps like IPhones, etc)
I created a test feed in both ASHX and ASPX format ... here is the code (I'm using Subsonic to populate the collection) ... are either of these along the correct lines?

I have written a code that go to controller using json and get the date from controller. Every thing works fine when running locally, but when i deploy my application to server, i am not getting the data returned from controller using jsonreturn. One more thing My firewall has blocked the GET. So how to resolve this.
//On Page
var URL = "/Home/AsyncGetCheapestList/" + param;
$.getJSON(URL, null, function(data) {
// displaying data content ;
});
//On controller
public JsonResult SetServiceIdServiceName(string asyncInputs)
{
List<string> st = new List<string>();
st.Add("one");
st.Add("two");
st.Add("three");
st.Add("four");
return Json(st,JsonRequestBehavior.AllowGet );
}
Here GET is blocked by my firewall so unable to get the data. Is that any other way to get it.
