asp.net custom HttpHandler and URL routing -


i want handle requests application "http://example.com/whateverpath" custom httphandler return things depending of value of "whateverpath".

so users accessing "http://example.com/path1" different response users accessing "http://example.com/path2", both request must handled in same httphandler. idea find "whateverpath" in database , depending of result, return response content.

i hear url routing , have custom http handler working, can combine both technique need?

i appreciate comment respect issue.

cheers frank abel

so have class implements ihttphandler called: myhandler , it's in namespace example, need make following entries in site's web.config in httphandlers section:

<httphandlers>   <add verb="*" path="*" type="example.myhandler"/> </httphandlers> 

since redirects urls web site/application handler have consider how serve static content (imgs, scripts, style sheets etc). 1 way store such static content in consistent url http://example.com/static/..., can set handlers such:

<httphandlers>   <add verb="*" path="*" type="example.myhandler"/>   <add verb="get,head" path="static/*" type="system.web.staticfilehandler" /> </httphandlers> 

for local dev webserver (embedded in visual studio) that's needed. iis, need tell iis how deal these urls (since server first analyses request decide send - including whether send asp.net or other extension).

  • open: iis manager ->
  • section: websites ->
  • right click on website ->
  • option: properties ->
  • tab: home directoy ->
  • button: [configuration...] ->
  • tab: mappings ->
  • section: "wildcard application maps (order of implementation):" ->
  • button: [insert...] ->
  • executable: "c:\windows\microsoft.net\framework\v2.0.50727\aspnet_isapi.dll" (or whichever version of .net runtime handler uses) ->
  • uncheck "verify file exists" ->
  • button: [ok]

now both iis , asp.net know how deal urls.

the above approach means when requesting static files, asp.net serving files, not iis - leads few disadvantages (discussed here). can override behaviour (disable wildcard mapping static directory) switching directory application (in iis manager), removing wildcard mapping statement (added above) , switching application. voilĂ  - static files handled iis without pestering asp.net.
