C# - Compressing Parameters In The URL?
Jan 13, 2010
The urls on my site can become very long, and its my understanding that urls are transmisted with the http requests. So the idea came to compress the string in the url.From my searching on the internet, i found suggestions on using short urls and then link that one to the long url. Id prefere to not use this soltuion because1) I would have to do a extra database check to convert between long and short url.
That leaves in my head 2 options1) Hashing, i dont think this is a option. If you want a safe hashing algorithim, its going to be long.2) Compressing the url string, basicly having the server depress the string when when it gets the url parameters.3) Changing the url so its not descriptive, this is bad because it would make development harder for me ( This is a 1 man project ).Considering the vast amount posible amount of OS / browsers out there, i figured id as if anyone else has tried this or have some clever suggestions.If it mathers the url parameters can reach 100+ chars.Example: mysite.com/Reports/Ability.aspx?PlayerID=7737&GuildID=132&AbilityID=1140&EventID=1609&EncounterID=-1&ServerID=17&IsPlayer=True
EDIT:Let me clarify atm this is NOT breaking the site. Its more about me learning to find a good solution ( Im well aware this is micro optimisation, my site is very fast atm ) and making my site even faster ( To challage myself, and become a better coder ).There is also a cosmetic issue, i personaly think that a URL longer then the address bar looks bad.

I agree that the best way to shorten the ViewState is to disable it on the ASP.Net controls that don't need it. Keeping it small from the beginning is a great habit.I have also heard that it is already compressed (although can be true... there are ways of compressing it even more, has described in this Stack Overflow question).
My question here is not if it should be compressed... is: when should ViewState be compressed?If we have a ViewState of 410 characters it will weight 410 bytes in a page, while a ViewState of 13.843 characters equals 13.5 KB.13.5KB is a considerable weight already. And if I compress a CSS file that height 10KB, I think it is also worthy compressing a ViewState of 13.5KB, even if that means a little extra "thinking" on the server.But is 410 bytes of ViewState worth the extra processing on the server?

I need to write a routine which uploads a largish (2-4 meg) jpg photo and shrink it down to a small size. Adobe image ready does what I need but I need to develop it in my web application. Basically I need to reduce the image file size so it is web friendly.

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]

Since ASP.NET MVC3 RC2 I encounter a bug when posting values to a controller method of which one of the parameter is a nullable int. Steps to reproduce:
I've created a test method
[code]....
In MVC3 RC1 this was working without any problems with the nullable int
Update:
I don't seem to have the problem with a newly created MVC3 website. What could I have in my project that influence model binding to nullable int's? And why would there be a difference between RC1 and RC2?

I am using jquery ajax method on my aspx page,which will invoke the webmethod in the code behind.Currently the webmethod takes a couple of parameters like firstname,lastname,address etc which I am passing from jquery ajax method using
data:JSON.stringify({fname:firstname,lname:lastname,city:city})
now my requirement has been changed such that,the number and type of parameters that are going to be passed is not fixed for ex.parameter combination can be something like fname,city or fname,city or city,lname or fname,lname,city or something else.So the webmethod should be such that it should accept any number parameters.I thought of using arrays to do so, as described here.
But I do not understand how can I identify which and how many parameters have been passedto the webmethod to insert/update the data to the DB.

I have two examples to show you what I want to achieve here. But to point what's different about my question, Is that I'm having a parametrized URLs and I want to implement URL rewriting to my application. But I don't want to convert the parameter in the URL to be placed between slashes..."page.aspx?number=one" to "pages/one/" << NOT!
First example:
http://localhost:1820/Pages/Default.aspx?page=2&start=5
To
http://localhost:1820/Pages/page2
Second example:
http://localhost:1820/Items/Details.aspx?item=3
To
http://localhost:1820/Items/ItemName
But I'll still need all the parameters in the original URLs

I have a stored procedure that works fine for classic asp, but how can I get my output parameters data back from in /MVC 2 / linq/ entities framework model . I have inported the function also, but when i try to code it i dont get results ...i know this is a matter of lack of / knowledge or exmple because i have been scouring the web for it and cannnot find into that accually works.
here is the stored proc.
[Code]....
Here was the one of the few tries I did:
[Code]....
but it executes fine does not give me an error, but also does not return the info i need to the viewmodel
I keep seeing stuff about "ref" on the net but "ref" shows " arbument # should not be passed with the ref keyword.
So i am not sure if there is a problem with the model, or with my understanding this, Now for your info I can do the same step with returning a dataset from a stored procedure fine, but I dont want a data set I just want excatly the data in the output parameters from the stored procedure.

I am an ASP beginner, I have a stored precodure which accepts two input parameters. In my ASP project, I have a button click event
protected void OnAddClick(object sender, EventArgs e)
{
string concept = txtConcept.Text;
string keyword = txtKeyword.Text;
.......
int result = Helper.ConceptInsert(concept,keyword);
}
In my Helper.cs, I have a method as
public static int ConceptInsert(string description, string keyword)
{
int result = -1;
string connString = ConfigurationManager.ConnectionStrings["MySpaceConnectionString"].ConnectionString;
string commString = "exec dbo.Concept_Insert @description";
using (SqlConnection conn = new SqlConnection(connString))
{
using (SqlCommand comm = new SqlCommand(commString, conn))
{
comm.Parameters.Add(new SqlParameter("@description", description));
comm.Parameters.Add(new SqlParameter("@keyword", keyword));
conn.Open();
result = comm.ExecuteNonQuery();
}
}
return result;
}
But when I run the code, error message is always Procedure or function 'Concept_Insert' expects parameter '@keyword', which was not supplied. How can I pass those two parameters together to the stored procedure?

I consider the following an error, and not a feature:
When posting a request, any parameters are held in the HttpContext.Request.Form as key/value pairs. This is perfectly fine for the recipient of the request. Unfortunately, however, further down the chain these values still exist and take precedent in binding over new parameters created during processing.
This is obvious in the RenderAction scenario. If a new parameter is created in a view and passed through RenderAction, if the parameter has the same name as one of the initial request parameters (or a form field for that matter), then MVC Binding will bind the initial request form value to the Action being called, and not the new parameter being defined in the RenderAction call. What's even more frustrating, is there is no easy way to override the initial form values.
It really does not make sense that a value defined in one context, should live throughout the entire processing context... at least without the developer being able to determine it should remain. At a minimum, any new parameter defined in the process with the same name should either a) be received as a parameter and not a form value; or b) override the form value.

In this answer to my question of how to insert data into SQL Server he mentioned passing parameters instead of string concatenation like I currently have.
Is this really necessary for security? If so, what exactly is passing parameters? When i google it I get a lot about stored procedures. Is that what I want, I do not know about stored procedures....yet.
EDIT:
Ok, here is what I got. It seems to update the database correctly and eventually I will change the hard coded ints to inputs from a label. confirm if how I did this is not vulnerable to any sql injection or hacks.

I need to be able to provide a page for the end user where thay can search in the following :
Search work
Category
Price
AdType
Location
and so on.
Its important that the user can copy the url and then use it later(and get the same settings). Its also important to be able to save these settings on the user in the database.
So far I have created a ModelView class that contains the parameters but I am not sure that this is the right way to go? Maby I should pass all inte the URL.

I have one page that I am dynamicaly creating a URL complete with two parameters that I need on the destination URL page in my stored procedure that I will be running a sql report with.
here is my url that is created
[URL]
my two parms are ReqID and CoOpCode.
I need to capture those two parms for my stored procedures I found some examples of doing it however the example only shoewed for the int and not the string.
I have heard some folks say use java and other say just do it in the code behind either way is fine by me I guess but I do like the code behind.
How can I do this?
Then the next question is how to I pass those parms to my Sql Report that using the stored procedure.

I know how to get back a single url parameter which is done using
string id = Request.QueryString["type"]
However, I am having problems passing and getting back two parameters. I am first passing the two parameters/argument using the following syntax
string name_one = "main"
string name_two = "category"
string needed_msg = "Zone.aspx?type=" + name_one + "&" + name_two;
Response.Redirect(needed_msg);
and I would like to get back the paramaters/arguments as two separate strings. How do I do it.

I have an asp.net 2.0 application which when it starts up need to read a number of parameters in order to enable the accessible functionalities for the user. It also needs to read database connection parameters among etc. I am currently using a singleton class to read all the parameters from an xml file. Is this the best way of doing this or should I add all the parameters in web.config? The app takes > 1minute to start How can I improve on the performance?

I have just finished converted a vb.net app to c# and one of the lines is to get @ReturnValue from the parameter.I ended up having to CAST a lot of things..Is there not a easier wayhere is what i have
int rc = ((System.Data.SqlTypes.SqlInt32)(((System.Data.SqlClient.SqlParameter)(cmd.Parameters["@ReturnValue"])).SqlValue)).Value;
In vb.net it was as simple as doing this
Dim rc As Integer = Convert.ToInt32(cmd.Parameters("@ReturnValue").Value)
Alot easier :-)But the problem with C# is the property Value isn't available unless I Cast to SqlParameter and i also need to cast to Sqltypes.SqlInt32 - i can't just do a standard Convert.ToInt32
