The following message apears:

Server Error in '/' Application.

Runtime Error

Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".

<!-- Web.Config Configuration File --><configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

<!-- Web.Config Configuration File --><configuration>
<system.web>
<customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
</system.web>
</configuration>

Thanks, Axel, for reporting the problem. I took some provisions that most like would make you do not experience this problem anymore. Please reports if you still will be having the problem.

I would like to pass a few worlds about the nature of the problem. It looks as you do not have this problem all time but only very occasionally, at least once as I can see it. I was trying to find a reason why but was not able to. You use very old browser MS Explorer 6.0, I see no reasons why. Nevertheless I installed the IE6 on one of my test boxes and had no problems operating the site. I have no error on my site log for days except your visit 6 hours back. I was wondering what it might be, particularly considering that you other visits were without any errors.

Then I spotted a very strange configuration of your internet service provider. The Server Variables of your request for REMOTE_ADDR and HTTP_X_FORWARDED_FOR are different. This is typical if your ISP makes you to use a proxy service and override your IP. I have seen in past as some “bad” proxy services inject into a request bunch of the data that shall not be there. I do not know what happen in your case. I know certainly that they do something funky as each single your request to my site comes from different IP of different subsets. Your visits so not even set a session as each single page you request is a separate brains new session from a brains new IP. I have no idea why they do it but it how your ISP operates.

My site runs quite heavy intrusion detection and under normal circumstance your visits would be alarming for my security. I knew about your ISP since you begin to post at my site and I permit the South Africa Bellville servers from ‘196.25.x.x’ and ‘198.54.x.x’ to behave a bit freely. Mind you that some of IP that your ISP uses are reported as spamming IP. This might be because your ISP offers own platform for some shadow internet operations.

Anyhow, you shall be set with my site but you might want to look deeper into what your Internet Service Provider does.
