Hi All,
I am a c# dev working on some code for a website in vb.net. We use a lot of caching on a 32bit iss 6 win 2003 box and in some cases run into OutOfMemoryException exceptions. This is the code I trace it back to and would like to know if anyone else has has this...
Public Sub CreateQueryStringNodes()
'Check for nonstandard characters'
Dim key As String
Dim keyReplaceSpaces As String
Dim r As New Regex("^[-a-zA-Z0-9_]+$", RegexOptions.Compiled)
For Each key In HttpContext.Current.Request.Form
If Not IsNothing(key) Then
keyReplaceSpaces = key.Replace(" ", "_")
If r.IsMatch(keyReplaceSpaces) Then
CreateNode(keyReplaceSpaces, HttpContext.Current.Request(key))
End If
End If
Next
For Each key In HttpContext.Current.Request.QueryString
If Not IsNothing(key) Then
keyReplaceSpaces = key.Replace(" ", "_")
If r.IsMatch(keyReplaceSpaces) Then
CreateNode(keyReplaceSpaces, HttpContext.Current.Request(key).Replace("--", "-"))
End If
End If
Next
End Sub
