.NET Forum / ASP.NET / General / September 2007URL Encoding Library / class whatever ?
OK, this is sort of a two part question here. The scencario is that I am building an article.aspx page which takes a parameter ( ArticleID ) and this represents an article in the database. This all works fine and as its a public site, google has index it. Now I read somewhere that adding extra information in the url might give the document score on google extra points so I thought, ok why not just add some hyphen seperated keywords to the parameter and simply strip those off when the articel.aspx loads, for example. Article.aspx ?ArticleID=9119_asp.net-2.0-xml-datagrid So the code inside discards everything from the '_' onwards and uses the numeric value to lookup the article. OK thats the easy bit. Because this is a url, Im assuming I cant use special characters like '.' '#'' etc etc as they have special meaning in the url. 1.) So Is the special character issue also applied to query strings, in other words, should they also be escaped as well. ? 2.) Does anyone have code like a set of regexes expressions or something which will automatically encode the special characters, what I guess Im looking for is something which will turn this for example Article.aspx?ArticleID=9999_asp.net, visual studio, xml, Into Article.aspx?ArticleID=9999_asp%nn-net-visual-studio-xml Any help would be apprciated > 1.)

Yes, though in this particular scenario you're essentially discarding the part of the querystring which might have caused you problems... However, it's good practice to do the encoding anyway... > 2.)

It seems you cant get to this functionality from a windwos based app. I cant seem to instantiate a httpserverutility class or make use of its functions. Server is an instrinic instance of this class in an asp.net web app, do you know if there is a way to instantiate it in a windows app, it shows an example of doing so, but without the new keyword, and of course you cant use that. >> 1.)

SignatureMark Rae ASP.NET MVP http://www.markrae.net Thanks mark, Im aware what the newsgroup was, it was just that I was testing it in a quicker environment. And I had already added a reference and could see the class in the namespace, but was unable to instantiate it, or use it as a static method. You try it and see if you can make it work, cos I cant ! :) >> Excellent answer for web based projects. > [quoted text clipped - 9 lines] > > 3) HttpUtility.UrlEncode(...) > Thanks mark, > [quoted text clipped - 4 lines] > > You try it and see if you can make it work, cos I cant ! Working fine for me: string strRawQS = "ArticleID=9119_asp.net-2.0-xml-datagrid"; string strEncodedQS = System.Web.HttpUtility.UrlEncode(strRawURL); SignatureMark Rae ASP.NET MVP http://www.markrae.net Odd, I was using vb rather than csharp, although that should not have made a difference, could you be so kind as to try it in vb for me Thanks >> Thanks mark, >> [quoted text clipped - 9 lines] > string strRawQS = "ArticleID=9119_asp.net-2.0-xml-datagrid"; > string strEncodedQS = System.Web.HttpUtility.UrlEncode(strRawURL); > Odd, I was using vb rather than csharp, although that should not have made > a difference, could you be so kind as to try it in vb for me Works perfectly: Dim strRawQS As String = "ArticleID=9119_asp.net-2.0-xml-datagrid" Dim strEncodedQS As String = System.Web.HttpUtility.UrlEncode(strRawQS) SignatureMark Rae ASP.NET MVP http://www.markrae.net Note that this is a shared methode ie. you don't need to create an instance of this class. If for some reason it's still doesn"t work your best bet is to describe what you have (i.e. the exact error message and the offending line of code). -- Patrice >> Odd, I was using vb rather than csharp, although that should not have >> made a difference, could you be so kind as to try it in vb for me [quoted text clipped - 3 lines] > Dim strRawQS As String = "ArticleID=9119_asp.net-2.0-xml-datagrid" > Dim strEncodedQS As String = System.Web.HttpUtility.UrlEncode(strRawQS) Must be me then, ill try it again Cheers >> Odd, I was using vb rather than csharp, although that should not have >> made a difference, could you be so kind as to try it in vb for me [quoted text clipped - 3 lines] > Dim strRawQS As String = "ArticleID=9119_asp.net-2.0-xml-datagrid" > Dim strEncodedQS As String = System.Web.HttpUtility.UrlEncode(strRawQS)
