IHttpHandlerFac tory interaction with VisualStudio

[John H Clark]

I am building an IHttpHandlerFac tory to process all requests to folders in my
site.

When an attempt to access internal folders is detected the request is
rerouted to an error page.

All other attempts are processed using

return PageParser.GetC ompiledPageInst ance(url, pathTranslated, context);

This results in a situation created when I start my solution in VisualStudio.

VisualStudio accesses a temporary page
"<domain>/<application>/vs-xxxxx-tmp.htm.

The result is that VisualStudio will not start the web project and says that
the physical location doesn't map to the URL.

What should the IHttpFactory return when it detects a visual studio start
attempt?

Is there a better way to gracefully leave the factory than via PageParser?

Any help would be appreciated.

Hi John, another thing i forgot to mention in my last post was to catch
requests for real items... in this case your .proj files
'Ignore real files
If Not IO.File.Exists( c.Server.MapPat h(c.Request.Url .AbsolutePath)) Then

'catch your .axd request and ignore processing them

Dim isAXD As Boolean = False
isAXD =
c.Request.Url.A bsolutePath.ToL ower.IndexOf("t race.axd") > -1

If Not isAXD Then
' do your processing here
End If


end if

Hi John, Sorry for the confusion, the "last post" was the one in the other
thread.

Here is an example of an IHttpModule which should ignore real files e.g. the
..proj files that VS needs when it connects to the web server. It is stripped
out of a project I'm working on at the moment. I've had to take quite a lot
of app specific stuff out and I haven't tested it but... HTH jd

Public Class ExampleModule
Implements Web.IHttpModule
Public Sub Dispose() Implements System.Web.IHtt pModule.Dispose

End Sub

Public Sub Init(ByVal app As System.Web.Http Application) Implements
System.Web.IHtt pModule.Init
AddHandler app.BeginReques t, AddressOf Application_Beg inRequest
AddHandler app.EndRequest, AddressOf Application_End Request
End Sub

Private Sub Application_Beg inRequest(ByVal o As Object, ByVal e As
EventArgs)
Dim app As Web.HttpApplica tion = CType(o, Web.HttpApplica tion)
Dim c As Web.HttpContext = app.Context

If Not IO.File.Exists( c.Server.MapPat h(c.Request.Url .AbsolutePath))
Then

Dim isAXD As Boolean = False
isAXD = c.Request.Url.A bsolutePath.ToL ower.IndexOf("t race.axd")

-1
If Not isAXD Then

c.Items.Add("St artTime", Now.Ticks)
'************** *************** *************** ******
'
' change this bit to use your own IHttpHandlerFac tory
' or Web.UI.PagePars er.GetCompiledP ageInstance
'
'************** *************** *************** ******

Dim pathTranslated As String

Dim myFactory As Web.IHttpHandle rFactory
c.Handler = myFactory.GetHa ndler(c, c.Request.Reque stType,
c.Request.Url.T oString, pathTranslated)
c.Handler.Proce ssRequest(c)
c.Response.End( )
End If
End If


End Sub

Private Sub Application_End Request(ByVal o As Object, ByVal e As
EventArgs)
Dim app As Web.HttpApplica tion = CType(o, Web.HttpApplica tion)
Dim c As Web.HttpContext = app.Context

Dim t2 As Int64 = Now.Ticks
Dim ts As Int64 = t2 - c.Items.Item("S tartTime")

Dim secs As Double = (1 / TimeSpan.FromSe conds(1).Ticks) * ts

'
' do not include the next line if you are streaming binaries!!!
'

'c.Response.Wri te("<!-- Page Processed in " + secs.ToString + "
seconds. -->")
End Sub

End Class
