c# - how to send a large URI using HttpWebRequest -


i'm using these lines fetch data company's server 

httpwebrequest request = (httpwebrequest)webrequest.create(url); request.credentials = new networkcredential(usr, pass); servicepointmanager.servercertificatevalidationcallback = ((sender, certificate, chain, sslpolicyerrors) => true); httpwebresponse response = (httpwebresponse)request.getresponse();

i got exception

{"the remote server returned error: (414) request uri large."}

at line:

httpwebresponse response = (httpwebresponse)request.getresponse();

so how can send large uri httpwebrequest?

thanks in advance

414 error code due long uri, have mentioned, length of supported uri can set @ web server if / company owns server can change setting meet needs, more information go here,

but guess should change approach here because 80% of uri filter parameter should find other way shorten parameter, can use json shorter xml & can used data communication
