View Full Version : webservice with long polling from ajax

21-05-2008, 05:16 PM
Getting long polling from ajax with an webservice (written in delphi.net) is more troublesome then i expected. It seems that my webservice (or the webserver for that manner) is only handling one connection at a time?

To see the effect try: http://strato.vanderhoning.net/default.htm . Once an second ie is opened things go haywire.

To disect the problem i have the following testcase:
Open http://strato.vanderhoning.net/Handler.ashx twice and then
Use http://strato.vanderhoning.net/VmsApi.asmx?page=op&tab=test&op=HelloWorldAddFeeder&bnd=TvmsApiSoap&ext=testform&name=ytestr to add a new text line.
Now only the first window updates.

Any ideas on what could be wrong are appriciated.

made the handler session aware and changed the method for detecting if new text was added.

new question:

What is the best method for reading out handler.ashx from delphi? I do not want to lock up the ui. E.g. once content is recieved it should read out handler.ashx once more.
