HTTP verb POST not allowed

Question

User-1344500247 posted

I have a web service that worked fine in VS2003 that is not taking the transition to VS2005 well. I've tried creating a "Hello World" test service, and it's not working either. The asmx page comes up fine, but when I click "invoke" I get this:

The HTTP verb POST used to access path 
'/Restoration/services/Test.asmx/HelloWorld' 
is not allowed.

I've added this to web.config

 <webServices>
   <protocols>
      <add name="HttpPost" />
   </protocols>
</webServices>

...but it doesn't make any difference. I'm guessing there's something very simple I'm overlooking - any ideas?

Thanks
Herb

Found the problem here - our URL rewriting code was making the web service unhappy. Excluded the web services from the URL rewriter and now it works.

I am still getting this problem while trying to use a .asp page in the application.

 

The HTTP verb POST used to access path ..... not allowed

I'm starting to think web services are quite the worse thing in ASP.NET you can get.

I have added in ISS all extensions "*" with all verbs to go to ASP.NET 2.0 handler  (aspnet_isapi.dll) so that I can use user-based authentication in .NET for all files on the server.

It works nicely, but messes up web services with this error:

The HTTP verb POST used to access path '..'   is not allowed.

what does one thing have to do with another is beyond me

I had a similar problem, and got very confused when I received the same error message. In my case, it only appeared when testing in the VS 2005 environment. Apparently the built in web server for VS does not allow running of ASP pages.

User-1555209197 posted

I had same problem. Having a web service and URL Rewriter in 2.0 is causing that problem. I think is a bug, appliaction should not call Rewriter is it is accesing ASMX.

So, what I did was:

In Global.asax.vb there is a function that call Rewriter, here the function:

Protected Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs)

If Not Request.Path.IndexOf(".asmx") >= 0 Then ' added to eliminate the error

 .....URLRewriter.Rewriter.Process()

End If

End Sub

if (Request.Path.IndexOf(".asmx") != -1)
{
	HandleAjax(context);
	return;
};

private static void HandleAjax(HttpContext context)
{
	int dotasmx = context.Request.Path.IndexOf(".asmx");
	string path = context.Request.Path.Substring(0, dotasmx + 5);
	string pathInfo = context.Request.Path.Substring(dotasmx + 5);
	context.RewritePath(path, pathInfo, context.Request.Url.Query);
}

I am sorry, where should this code be placed? Does it fixed problem with adding .* verb in IIS for URL Rewriting? I have the same error with Ajax Toolkit - Slides control... Please help

Answer 10

User-1329334484 posted

In fact I have disabled URL rewriting, just adding *.ver in ISS is causing this problem. What should I do?

Answer 11

User-1329334484 posted

I have tried your code, but it does not work. where should I put it in BeginRequest?

I get comiplation error, It says that context is unknown...

void Application_BeginRequest(Object Sender, EventArgs e)

{

if (Request.Path.IndexOf(".asmx") != -1)

{

HandleAjax(context);

return;

};

}

 

 

private static void HandleAjax(HttpContext context)

{

int dotasmx = context.Request.Path.IndexOf(".asmx");

string path = context.Request.Path.Substring(0, dotasmx + 5);

string pathInfo = context.Request.Path.Substring(dotasmx + 5);

context.RewritePath(path, pathInfo, context.Request.Url.Query);

}

Answer 12

User-1329334484 posted

I am also having problems after wildcard applied in ISS. This time Slides Control from Ajax Toolkit does not work. You will get this Java Script error: HTTP verb POST not allowed

I wonder maybe I need to do the same code for .axd files, but after I tried the same with .axd files, I get "Sys not defined" and "Type not defined" errors...

Would you know what correct code is for .axd files?

Hi,

I've meet same problem when i've tried to use a linkbutton in aspx page that should redirect to a htm page, and put on linkbutton:

PostBackUrl="~/coco.htm".

I've solved my problem by using:

<a href="coco.htm">

Coco</a>

 Maybe you find this usefull.

I eliminated the problem by removing the mapping of ‘*’ to aspnet_isapi.dll in my IIS settings.

Answer 17

User255832318 posted

I have URL rewriting (UrlRewrite.net) and need to map * to aspnet_isapi.dll

I found a solution for the asmx issue :

      <add name="ScriptHandlerFactory" path="*.asmx" verb="GET,HEAD,POST,DEBUG" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework64\v2.0.50727\aspnet_isapi.dll" resourceType="Unspecified" requireAccess="Script" preCondition="classicMode,runtimeVersionv2.0,bitness64" responseBufferLimit="0" />
 

put this into  

<system.webServer>
    <handlers>

tags.

 

It solved everything for me. URL-RW and WS calls (autocomplete Ajax WS call) are working fine :)

 

i hope this could help.

 An alternative I found elsewhere in the forums is to call in javascript PageMethods.set_path('/page.aspx'); with the real virtual path not the url friendly path. This will then work with any url rewriting engine.

Complete Solution is As below for every url rewrite engine

In you Global.ascx file just copy paste the code below.

 protected void Application_BeginRequest(Object sender, EventArgs e){if(Request.Path.IndexOf(".asmx") != -1) // if the url contains .asmx extention

{

SendRequestWithSimpleURL(Context);

return;}else{

 

ThunderMain.URLRewriter.Rewriter.Process(); // this is my URL rewriter Code. Paste your Code for url rewriting

}

}

private static void SendRequestWithSimpleURL(HttpContext context)

{

int asmx = context.Request.Path.IndexOf(".asmx");

string path = context.Request.Path.Substring(0,asmx + 5);

string pathInfo = context.Request.Path.Substring(asmx + 5);

context.RewritePath(path,pathInfo,context.Request.Url.Query);

}

Thats All it will work fine. Thank you & dont forget to tag as answer if it helps you.

Answer 24

User1639034410 posted

finally i found the solution from above code it self.

you just need to change you context with HttpContext.Current

if (Request.Path.IndexOf(".asmx") != -1)
        {
            HandleAjax(HttpContext.Current);
            return;

I have tried your code, but it does not work. where should I put it in BeginRequest?

I get comiplation error, It says that context is unknown...

void Application_BeginRequest(Object Sender, EventArgs e)

{

if (Request.Path.IndexOf(".asmx") != -1)

{

HandleAjax(context);

return;

};

}

private static void HandleAjax(HttpContext context)

{

int dotasmx = context.Request.Path.IndexOf(".asmx");

string path = context.Request.Path.Substring(0, dotasmx + 5);

string pathInfo = context.Request.Path.Substring(dotasmx + 5);

context.RewritePath(path, pathInfo, context.Request.Url.Query);

}

        }

from this my code working perfect...

may be it helps...

Thanx for the idea.
