I am really sorry to post this question, because most likely the solution will be really simple. But I am completely out of search string ideas.
I have a running Geoserver and some custom shapefiles describing buildings etc. I can requesting maps as pngs with the WMS interface and display on a website. So for so good.
In the next step I want to enable the user to specify a coordinate an draw a little marker on the map. This position should not be stored anywhere, I just want to draw it for this user. I am pretty sure this is possible with a WMS request and an inline feature, but I had not any luck finding a working solution and I am out of google search strings.
Please help me before I start drawing overlays over a png map.
