AJAX IIS7: java

Hi, I have created a webservice for putting overlays on googlemap. I am using scriptmanager to generate java proxy class. Everything works as expected as long as I use localhost in the url e.g.http://localhost/test.aspx orhttp://localhost/map.asmx/js but if I use the actual domain name then it don't work anymore e.g.http://www.test.com/test.aspx orhttp://www.test.com/map.asmx/js. In case of IE7 i get script error 'test is undefined' and in case of Firefox, I get authentication failed. The result is same whether I run it on the server or on the client. I have tried every possible thing that I can think of. Environment is Win 2003 and IIS 6.0. Framework 2.0 is enabled in the web services entensions. I am using windows integrated authentication and anonymous access is also enable. I am new to ajax world and trying hard for last 2 days to solve this problem. Please help me. Thanks a lot

Hi,

Can you directly browse to http://www.test.com/map.asmx/js. and does that download the Script Proxy ?

Also , can you take a look at the IIS Logs to understand the behavior on the server when you browse to the page ?

Go to Start --> Run -->Type in "LogFiles"

In the folder that opens up , go inside W3SVC1.

Take a look at the File exmmddyy.log and paste the lines that havemap.asmx/js. here.

Thanks for quick response. When I directly browse to .../js in IE7, i get 500 internal error whereas in case of Firefox, it prompts to download a file and the contents of the file are: "{"Message":"Authentication failed.","StackTrace":null,"ExceptionType":"System.InvalidOperationException"}".

No such folder "W3SVC1" exists under LogFiles ... only following folders are present there "Cluster, HTTPERR, ShutDown" and in there I am not able to find anything related to my issue.

Please let me know what next I should do? Thanks

Hi,

HttpPost andHttpGet for webservices is disabled by default in ASP.net 2.0

See if you can find the following snippet in your web.config , if it doesnt exist, add it under the <System.Web> Tag

<webServices>
<protocols>
<add name="HttpSoap1.2"/>
<add name="HttpSoap"/>
<add name="HttpPost"/> // uncomment this
<add name="HttpGet"/> // uncomment this
<add name="HttpPostLocalhost"/>
<add name="Documentation"/>
</protocols>
<soapExtensionTypes>
</soapExtensionTypes>
<soapExtensionReflectorTypes>
</soapExtensionReflectorTypes>
<soapExtensionImporterTypes>
</soapExtensionImporterTypes>
<wsdlHelpGenerator href="http://links.10026.com/?link=DefaultWsdlHelpGenerator.aspx"/>
<serviceDescriptionFormatExtensionTypes>
</serviceDescriptionFormatExtensionTypes>
</webServices>

Hope this helps

Yes, it was not there and I copied it under system.web tag but the issue is still there. There is also an <httpHandles> tag under system.web. I am pasting the lines from my web.config related to ajax. May be it will give further clue. Please let me know if u see something wrong there or what should I do next. Thanks a lot.

I have found the iis logfiles and the directory 'W3SVC1' ... this directory is present in another partition because of setting different path for logging from IIS console.

Below are the lines related to this webservice:

this is the line when called with the following url : http://localhost/WebServices/WSGoogleMaps.asmx

2007-02-22 17:06:54 127.0.0.1 GET /webservices/wsgooglemaps.asmx/js - 80 - 127.0.0.1 Mozilla/5.0+(Windows;+U;+Windows+NT+5.2;+en-US;+rv:1.8.1.1)+Gecko/20061204+Firefox/2.0.0.1 200 0 0

and this is the line when called with the following url: http://mytest.server.com/WebServices/WSGoogleMaps.asmx

2007-02-22 18:15:27 192.167.1.273 GET /WebServices/WSGoogleMaps.asmx/jsdebug - 80 - 132.136.112.84 Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+5.1;+InfoPath.2;+.NET+CLR+2.0.50727;+.NET+CLR+1.1.4322) 500 0 0

I have tried it on the server itself as well. If I use domainname then it is giving 500 internal error in IE7 or authentication failed in Firefox. This is the line when called from the server itself using domain name:

2007-02-22 16:41:04 192.167.1.273 GET /WebServices/WSGoogleMaps.asmx/jsdebug - 80 - 192.167.1.273 Mozilla/5.0+(Windows;+U;+Windows+NT+5.2;+en-US;+rv:1.8.1.1)+Gecko/20061204+Firefox/2.0.0.1 500 0 0

I simply don't understand that how same code on the same machine works with localhost in the url but gives error when called with domain name in the url. I am totally lost. Please help me solve it ... I need to solve it urgently. Thanks.

Hi there,

We are experiencing the same issue that seems to do with the domain name causing the authentication error in some environments. Did you ever get a resolution to this issue?

Hello Developers,

I spent half a day pulling my hair out, before I figured out that changes I make to my java scripts do not make it to the browser. The same problem applies to *.css files. It is a well known problem - resources requested by GET are being cached, and changing Response.Cache settings seems to make no impact.

There are some ways around, like adding a unique request parameter, but it is rather inconvenient.

Is there any proven solution which could be implemented on the global application level to allow effective AJAX development, like some tweaking in one of the global events?

I am wondering how ASP.Net Development Team handles this issue.

Thank you for any help.

Mine normally doen'st cache if I have compilation debug='true' in the config file.

Hi,

Mine apparently does :(
Why would caching be different in debug mode?

Here is what seems to work, but may be there is a better way.

void Application_PreRequestHandlerExecute(object sender,EventArgs e){
HttpContext context =HttpContext.Current;
TimeSpan cacheDuration =TimeSpan.FromSeconds(1);
context.Response.Cache.SetCacheability(HttpCacheability.Public);
context.Response.Cache.SetExpires(DateTime.Now.Add(cacheDuration));
context.Response.Cache.SetMaxAge(cacheDuration);
context.Response.Cache.AppendCacheExtension("must-revalidate, proxy-revalidate");

}

There is a setting in the web.config file which caches the javascript file to reduce the downloading of the Ajax Framework scripts also those which are added by the scriptmanager script references. But i think the defaut value is not cache the js files. You try this setting enable/disable caching.

<scriptResourceHandlerenableCompression="true"enableCaching="false"/>

I am not sure about the Css files caching, the default is cached i think and setting response.cache will not make any impact as the css files are handled by IIS instead of Asp.net runtimes unless you sepcify same asp.net handler for css too.

Although I read this setting applies to server caching only, it seems to work, so it probably also modifies the response header and tells the client not to cache.

Thank you for your help. I was unaware of this setting. By default it is commented out.

In VS 2005 dev environment requests to static content (well, at least *.css, *.jpg and *.gifs) go through asp.net. With IIS the story is, or can be different.
