ASP Page executed twice

Hi

I have an ASP page which is randomly (?) executed twice. I noticed that the
http header is different, as if there are two different requests sent to the
server. Header 2 below is the one that randomly occur.

Although the 2 headers are different I don't understand why

Help will be greatly appreciated

Thanks

Hi again

I resolved this issue, and wanted to share the solution as it may be of some
help to others.

On the specific page I was having a problem I am creating HTML code on the
client side using the JavaScript 'document.write' method. One of the tags I
am creating is an image <img src="" ... />. My plan was to populate the
image at a later point so I left the 'src' property empty, which was a
mistake... The img.src property is required, so the browser assumes that an
empty img.src property means the root URL, and was sending another GET HTTP
request and reloading the entire home-page.

Moral: don't leave the img.src property empty...

:-)
