I'm trying to access a webservice that returns a map image in different formats. It first always returns a .png file until I hit the refresh button. It then returns me the map in the correct format. Do you know what could cause that? Thank you.

Which refresh button are you hitting? The one in ArcGIS Server Manager, or the one in your browser? –  mwalker Mar 21 '11 at 20:38
Which browser are you using? I tried a similar query on ArcGIS online servers as well as my servers & it returns different formats, every time I change the 'FORMAT'. Can you clarify your question further? –  Devdatta Tengshe Mar 23 '11 at 3:01
