Dear Edvard Ananyan,
many thanks for your answer.
I asked to the company where I have the server and he said that IIS properly supports ISAPI filters; I do not know if what you say is something different from what is usually already installed in IIS; for php there is no problem because it is installed in the server, there would be a way to do a try?
Maybe you mean the ISAPI_Rewrite Lite version I see at http://www.isapirewrite.com/
Here you can see the limitations of the Lite version:http://www.helicontech.com/isapi_rewrit ... itever.htm
Do it work also with this version?
