ASP.NET – The HTTP verb POST used to access path … is not allowed

Here’s my contribution to the search engine troubleshooter’s knowledge base.

I was trying to fire up an ASP.NET web service (.asmx) on my development machine after several months of not using it. I was getting the error:

“The HTTP verb POST used to access path ‘[my web service’s URL]’ is not allowed”.

I eliminated the problem by removing the mapping of ‘*’ to aspnet_isapi.dll in my IIS settings. I had introduced this while experimenting with URL Rewriting and Castle MonoRail.

Hope that helps someone!

    Hi,

    I am getting the same error with my webservice, and most surprisingly it has started coming coming only from today! My application is built in ASP.NET 2.0. This is created as project, not as website. So, how can I make any change in the ISAPI? Please help…

    Regards,
    Niladri

    I have the same problem with Linkbutton and I solved the problem by redirect the web page in the code behind, see below.

    Pricing Strategy Matrix Reference Guide

    Private Sub lnkReferenceGuide_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lnkReferenceGuide.Click
    Response.Redirect(“~/Documents/PriceStratRefGuide.doc”)
    Me.GroupMLOTables.Visible = True
    End Sub
