What does pending mean for request in Chrome Developer Window

Question

What does  Pending  mean under the status column in the  Network  tab of Google Chrome Developer window   This happens when my page script issues a GET request whose response contains content-headers for downloading a CSV file   Content-type  text csv  Content-Disposition  attachment  filename myfile csv   This works fine in FF and IE7  downloading a CSV file as expected and opening a file picker to save the file  but Chrome does nothing   I confirmed that the server responds to the request  so it appears that Chrome will not process the response   Curiously  all works as expected if I type the URL into Chromes address bar and hit    FYI  Chrome 10 0 648 204 on Win-XP

I had a similar issue with application json ajax calls   In ff IE they were fine   In chrome in the Developer Network window Status was always  pending  because a different status code was being returned      In my case I changed my Json response to send a HttpStatusCode of 200 then Chrome was fine and the Status Text changed to 200 OK   For example using ASP NET Web Api   return new HttpResponseMessage HttpStatusCode OK                 Content   request Content

I also get this when using the HTTPS everywhere plugin  This plugin has a list of sites that also have https instead of http  So I assume before the actual request is made it is already being cancelled somehow   So for example when I go to http   stackexchange com  in Developer I first see a request with status  terminated   This request has some headers  but only the GET  User-Agent  and Accept  No response as well   Then there is request to https   stackexchange com with full headers etc    So I assume it is used for requests that aren t sent

I had some problems with pending request for mp3 files  I had a list of mp3 files and one player to play them  If I picked a file that had already been downloaded  Chrome would block the request and show  pending request  in the network tab of the developer tools   All versions of Chrome seem to be affected   Here is a solution I found   player 0  setAttribute  src   video webm dummy     Date now       You just add a dummy query string to the end of each url  This forces Chrome to download the file again   Another example with popcorn player  using jquery     url     this  find   url song   attr  url    pop   Popcorn smart    player     url     i     Date now       This works for me  In fact  the resource is not stored in the cache system  This should also work in the same way for  csv files

The Network pending state on time  means your request is in progressing state  As soon as it responds the time will be updated with total elapsed time   This picture shows the network call is in processing state Pending    This picture shows the time taken in processing by network call

In my case  I found  after much hair-pulling  that the  pending  status was caused by the AdBlock extension  The image that I couldn t get to load had the word  ad  in the URL  so AdBlock kept it from loading   Disabling AdBlock fixes this issue   Renaming the file so that it doesn t contain  ad  in the URL also fixes it  and is obviously a better solution  Unless it s an advertisement  in which case you should leave it like that

Same problem with Chrome   I had in my html page the following code      lt body gt           lt script src  http   myserver lib load js  gt  lt  script gt         lt  body gt    But the load js was always in status pending when looking in the Network pannel   I found a workaround using asynchronous load of load js     lt body gt           lt script gt      setTimeout function          var head  script        head   document getElementsByTagName  head   0         script   document createElement  script          script src    http   myserver lib load js         head appendChild script          1      lt  script gt         lt  body gt    Now its working fine

I had the same issue on OSX Mavericks  it turned out that Sophos anti-virus was blocking certain requests  once I uninstalled it the issue went away    If you think that it might be caused by an extension one easy way to try and test this is to open chrome with the  --disable-extensions flag to see if it fixes the problem  If that doesn t fix it consider looking beyond the browser to see if any other application might be causing the problem  specifically security apps which can affect requests
