Recently errors with PROXY are becoming more and more common during vcpkg usage, I'd move completely to aria, is there any regression in doing so? IMHO, this is a never-ending story with no happy end.

Proxy support as well as file protocol worked in the past but are broken in current versions. The move to WinApi was one regression, the move to aria2 the next one. See my issues, Before talking about the issue of downloading, it is just plainly annoying that pwsh. I noticed that not all ports are running pwsh probably somewhere in the scripts clearly indicate the name. A clean vcpkg installation on windows fails to download powershell, 7-zip and nuget just at the beginning, when installing your first library.

I still didn't inspect why, but these downloads are done in a different way broken, it seemsbecause they are totally not tested for proxy support. Also the fact that proxy support is so weak that usually I prefer to do the "download-only" part on the WSL side is depressing same pc, same proxy, somehow the linux part is more proxy resilientso that I don't fear of finding the update stopped because one of the library failed to download never happened when not using proxy.

Just to let you know, vcpkg on windows is the only program that gives me any problem with "dropped internet connection", so i'd not declare our proxy as guilty. Also, even when vcpkg is failing repeatedly, any browser installed can download the tar. Please fix it. For any enterprise adoption of vcpkg, a proper proxy support is a deal breaker.

It's still far from being here. We have exactly the same issue in our organisation.A pointer to a string that contains the additional headers to append to the request.

An unsigned long integer value that contains the length, in characters, of the additional headers. If this parameter is -1L and pwszHeaders is not NULLthis function assumes that pwszHeaders is null -terminated, and the length is calculated. A pointer to a buffer that contains any optional data to send immediately after the request headers.

The optional data can be the resource or data posted to the server. This buffer must remain available until the request handle is closed or the call to WinHttpReceiveResponse has completed. An unsigned long integer value that contains the length, in bytes, of the optional data.

This parameter can be zero if there is no optional data to send. An unsigned long integer value that contains the length, in bytes, of the total data sent. This parameter specifies the Content-Length header of the request.

If the value of this parameter is greater than the length specified by dwOptionalLengththen WinHttpWriteData can be used to send additional data. If dwTotalLength needs to be changed, the caller should create a new request. A pointer to a pointer-sized variable that contains an application-defined value that is passed, with the request handle, to any callback functions.

For extended error information, call GetLastError. Error codes are listed in the following table. An application must not delete or alter the buffer pointed to by lpOptional until the request handle is closed or the call to WinHttpReceiveResponse has completed, because an authentication challenge or redirect that required the optional data could be encountered in the course of receiving the response.

The WinHttpSendRequest function sends the specified request to the HTTP server and allows the client to specify additional headers to send along with the request.

This function also lets the client specify optional data to send to the HTTP server immediately following the request headers. An application can use the same HTTP request handle in multiple calls to WinHttpSendRequest to re-send the same request, but the application must read all data returned from the previous call before calling this function again. The name and value of request headers added with this function are validated. Headers must be well formed. The invalid header is not added.

Not enough memory was available to complete the requested operation. The content length specified in the dwTotalLength parameter does not match the length specified in the Content-Length header.In order to simulate the required timeout, try this workaround: after receiving an early timeout error, subtract the elapsed period from timeout, set the new timeout, and then repeat the operation in a loop.

Is this a known bug? I couldn't find any related info elsewhere. This timeout is essentially deprecated due to performance enhancements in the TCP stack in the latest versions of Windows. The TCP timeout is about retransmits with back-off and how many is tried by the Winsock stack.

Thx, David Microsoft - Windows Networking team. Friday, May 13, PM.This default 30 sec time is because of the use of WinInet Replay engine.

I wouldn't recommend that. View solution in original post. Thabjs for the suggestion but I already did that before you suggested. Unfortunately even with that it gives me same error. You can see in part of the replay you posted the errors come from resources during the replay where they timed out.
