Apache - IIS - different results (no replies)

Hello All

I have come up against a difficult issue.

This is WebDev 19.
Dev env. is using Apache 2.2
Prod is using IIS 7.5 on Window 2008 R2

This *may* be a Windows issue with some patch - but I can't really find any clues.

I have a "list" populated with person information and including a photo (image). When the person is selected - the details are copied to the main part of the page.

This works perfectly in the Dev env (Windows 10 client running local Apache server / and Windows 2008 R2 Server for HFSQL).

Also - I am pretty certain that this *was* working on Prod with IIS but I cannot be 100% certain as this code has not yet been released - there is a possibility that it could be an old issue that was missed.

The list is populated using a Looper control and LooperAddLine code.

When selected (clicked) - the server code assigns the the looper line attributes to the display area (i.e. name, details, and image/photo).

Now - when run on the production server - as soon as the image assignment line is reached - my session just disappears. I get no error condition - only that the next line says that the session was exited normally.

The code involved is simply : IMG_CONTACT_SELECTED = gsImagefile

I have tried many variations - changed the image attributes - checked all server permissions - but I am still clueless as to what is really going on.

I doubt it is a resource problem - as everything else just hums along fine. It simply bombs out when I assign the image value to the image control.

I am really hoping that I have just done something really stupid here that someone can point out - or give a clue as to how to debug this ...

Anyone got any clues? Windows OS? IIS? WebDev?

Thanks for any suggestions ..

Regards
Derek
