url rewriting3/5/2008 1:50:54 AM

0/0

 masterpage head section.

<head runat="server">
    <title>BorkedGuild.net Forum</title>
    <link href="~/css/forum.css" rel="stylesheet" type="text/css" runat="server" />
    <link href="~/css/TopLine.css" rel="stylesheet" type="text/css" runat="server" />
    <asp:ContentPlaceHolder ID="head" runat="server">
    </asp:ContentPlaceHolder>
</head>

I have then implemented a urlrewriter.

 

1            public void Init(HttpApplication context)
2            {
3                context.BeginRequest += new EventHandler(context_BeginRequest);
4            }
5            void context_BeginRequest(object sender, EventArgs e)
6            {
7               
8    
9             
10               HttpApplication app = (HttpApplication)sender;
11               Match oMatch = Utilities.rx.Match(app.Request.RawUrl.ToLower());
12               
13               if (oMatch.Success)
14               {
15                   string newUrl = Utilities.rx.Replace(app.Request.RawUrl.ToLower(), "/board/Default.aspx?f=$1");
16                   app.Context.RewritePath(newUrl,false);
17               }
18   
19           }
  What happens is that when i request an url that the oMatch does not success on. Then it only runs context_BeginRequest one time(http://localhost:49403/BorkedGuild.net/board/default.aspx?f=1). When I enter a url that my match find,(http://localhost:49403/BorkedGuild.net/board/1/) THen it first as expected does (have pasted the string it generate here) app.Context.RewritePath("BorkedGuild.net/board/default.aspx?f=1",false), but then with some breakpoints enabled, it pops again on line 6 two times where the 
app.Request.RawUrl is equal to:
		RawUrl	"/BorkedGuild.net/board/1/BorkedGuild.net/css/forum.css"	string
 		RawUrl	"/BorkedGuild.net/board/1/BorkedGuild.net/css/TopLine.css"	string
 which clearly is why my css is broken on the returned page.
 
Any comment on why its sending the request to the urlrewriter this second time for the css links but not the first time(based on when a not matched link is requested it do not hit the breakpoint at line 6 for the css links).

When you open a page in the browser it may cause several Application_BeginRequests on the server. For example every linked css and image will cause another request so you must not rerwite just the first request. Your code must also match other requests and rewrite them as well.

Good Luck!

It seems currently Utilities.rx class is handling only your .aspx page and not the ascociated reources and hence for all other css file oMatch.Success is false.
You need to modify your Utilities.rx class to handle css files too and also you need to remove the hard coded path "/board/Default.aspx?f=$1" and make it dynamic depending on the RawUrl.

 Hope this helps you...

Oki, thats what i missed then.

 

 public static Regex rx = new Regex("/board/([0-9]*)/*$", RegexOptions.Compiled | RegexOptions.IgnoreCase);

 

Gotta get that matching all other links also. I actuly belived the css/links and such was relative to the aspx page, aka doing app.Context.RewritePath(newUrl,false); it would fetch the links from that url instead.

Aint this url rewriting abit "expensive" then, if it on every request have to do some regex matching and such?

 Im not sure i understand why, after it did the rewritePath on the aspx page, and it next comes to the css link and the rawurl is  "/BorkedGuild.net/board/1/BorkedGuild.net/css/forum.css"   where the base url was /BorkedGuild.net/board/1/ and the aspx page was succesfull rewritten to /BorkedGuild.net/board/default.aspx?f=1

Without me doing anything, it manage to dod the right urls for the script objects.

<link href="BorkedGuild.net/css/forum.css" rel="stylesheet" type="text/css" /><link href="BorkedGuild.net/css/TopLine.css" rel="stylesheet" type="text/css" />

 And the only thing missing in the above css links is the / infront of it.

<script src="/BorkedGuild.net/WebResource.axd?d=_xqoAC_y7luLaqnRFtp75Q2&amp;t=633371676355755775" type="text/javascript"></script>


<script src="/BorkedGuild.net/ScriptResource.axd?d=BjTbBXg2XH_V1XmJZ7yHuwSXPH-5-fDb3Wg5BXc85TCeSrlvV3UUmrU56yYz9IJKvRe5X8yQfCLMoTgHz2ltIqCKU4Xx5K6B4xOiP_91F7w1&amp;t=633371680858375775" type="text/javascript"></script>

 Solved my problems by changing my masterpage css links.

    <link href="<%=ResolveUrl("~/css/forum.css")%>" rel="stylesheet" type="text/css" />
    <link href="<%=ResolveUrl("~/css/TopLine.css")%>" rel="stylesheet" type="text/css" />

 

But thx for the help, and questions about performens about urlrewrite is still open
