RFC 2396 section 4 1      When a URI reference is used to perform a retrieval action on the      identified resource  the optional fragment identifier  separated from      the URI by a crosshatch       character  consists of additional      reference information to be interpreted by the user agent after the      retrieval action has been successfully completed   As such  it is not      part of a URI  but is often used in conjunction with a URI     emphasis added

Just to rule out the possibility you aren t actually trying to see the fragment on a GET POST and actually want to know how to access that part of a URI object you have within your server-side code  it is under Uri Fragment  MSDN docs

We had a situation where we needed to persist the URL hash across ASP Net post backs  As the browser does not send the hash to the server by default  the only way to do it is to use some Javascript    When the form submits  grab the hash  window location hash  and store it in a server-side hidden input field Put this in a DIV with an id of  urlhash  so we can find it easily later  On the server you can use this value if you need to do something with it  You can even change it if you need to  On page load on the client  check the value of this this hidden field  You will want to find it by the DIV it is contained in as the auto-generated ID won t be known  Yes  you could do some trickery here with  ClientID but we found it simpler to just use the wrapper DIV as it allows all this Javascript to live in an external file and be used in a generic fashion  If the hidden input field has a valid value  set that as the URL hash  window location hash again  and or perform other actions    We used jQuery to simplify the selecting of the field  etc     all in all it ends up being a few jQuery calls  one to save the value  and another to restore it   Before submit      form   submit function          input     urlhash   val window location hash         On page load   var hashVal      input     urlhash   val    if  IsHashValid hashVal       window location hash   hashVal      IsHashValid   can check for  undefined  or other things you don t want to handle   Also  make sure you use   document  ready   appropriately  of course
