c# - PDF does not reload on directory browsing -


hi guys follow question , think real issue here. click here

whenever access file using directory browsing (eg. http://localhost/temp/1.pdf) render old or previous pdf file if change entire file same file name, example have 1.pdf content delete file on directory replace new , different content , rename 1.pdf when access using browser render previous value not new 1 replace. happens on ie , opera browser. please need production issue.

edit: found strange, example have url location of pdf file (eg. http://localhost/website/tempfolder/1.pdf) first pdf generated show part in code change casing of letter example 't', change 't' newly pdf shows when revert old case expecting show new pdf sad first pdf file shows.

your browser caching pdf files.

for ie, can ctrl f5 force reload web server. or put random query string in url e.g. /temp/1.pdf?v=1, /temp/1.pdf?v=2

assuming server iis, permanent solution configure http response headers.

go iis manager

navigate folder

click "http response headers" in features view

right-button click/select "set common headers"

check "expire web content" , select "immediately".
