.net - Cannot disable proxy caching -


i've got c# web client application uses restsharp library access third party web service. in environments has work via proxy. i'm using webproxy framework class provide proxy details , works fine. except 1 edge case.

the proxy (squid in case) configured require credentials.

if code sends request with webproxy credentials , after (less minute) (exactly same in case) request without credentials, nevertheless receive ok response instead of 407 (authentication required) error.

i've tried multiple suggestions found here , in other internet resources:

  • using cachepolicy nocachenostore
  • defining "cache deny all" in squid
  • calling "deleteurlcacheentry" of wininet.dll
  • providing random timestamp parameter make request url unique
  • adding cache control headers request

to no avail. i'm pretty sure restsharp not blame able trace execution inside library point uses underlying .net apis. restsharp respects both proxy , caching policy settings , passes them on .net classes.

i have not tried yet other proxies - squid.

i'd glad hear ideas and/or suggestions in solving problem.

regards,

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
