This is the archive of the web page resulting from the ASP query.

Hi,

I have serious doubts about Microsoft Internet technologies, but here is my finding anyway.

I need to use a web app built on ASP. As I could not script the communication with website, esp. "actions" (giving commands), because I could not reverse engineer the browser's ASP queries, I started on GUI scripting. As bad as it sounds, I made some progress automating some tab and enter keystrokes — but as some actions were not available that way (WebKit/Safari skips the link while it cycles through all the rest…), I even scripted mouse clicks.

And then I found out that the very same ASP queries (e.g. exact same searches on the website) result in different rendering of the resulting table (wider/narrower), which needless to say, breaks my careful mouse click coordination. Apart from my travails, I also got curious whether this is some lame functioning of ASP, of WebKit itself does something differently each time around.

I am sorry that I am not able to describe the whole process in more detail, I am no web designer nor programmer, but I have archived the web page resulting from the query (attached), if that helps. I guess application data and resources encrypted won't help much though.

Thank you for looking into this,

Laszlo

When I open the attached web archive in Safari 5, it seems to look fine. What rendering problem does it have?

The table is sometimes narrower, sometimes wider. The cell sizes or the line breaks within cells are unstable.

Apart from the screenshots, now attached, I can show you both instances in the format of web archives. Strikingly, both are rendered the same in Safari once saved ("offline"), but not live on the web ("online").
